Widget toolkits

object-oriented framework for GUI creation

GTK (formerly GIMP ToolKit and GTK+) is a free open-source widget toolkit for creating graphical user interfaces (GUIs) targeted at Linux and specifically GNOME (though with some use in other desktop environments). It is licensed under the terms of the GNU LGPL, allowing both free and proprietary software to use it.

wxWidgets (formerly wxWindows) is a widget toolkit and tools library for creating graphical user interfaces (GUIs) for cross-platform applications. wxWidgets enables a program's GUI code to compile and run on several computer platforms with no significant code changes. A wide choice of compilers and other tools to use with wxWidgets facilitates development of sophisticated applications. wxWidgets supports a comprehensive range of popular operating systems and graphical libraries, both proprietary and free.

GNUstep is a free software implementation of the Cocoa (formerly OpenStep) Objective-C frameworks, widget toolkit, and application development tools for Unix-like operating systems and Microsoft Windows. It is part of the GNU Project.

PyQt is a Python binding of the cross-platform GUI toolkit Qt, implemented as a Python plug-in. PyQt is free software developed by the British firm Riverbank Computing. It is available under similar terms to Qt versions older than 4.5; this means a variety of licenses including GNU General Public License (GPL) and commercial license, but not the GNU Lesser General Public License (LGPL). PyQt supports Microsoft Windows as well as various kinds of UNIX, including Linux and macOS.

PyGTK is a set of Python wrappers for the GTK graphical user interface library. PyGTK is free software and licensed under the LGPL. It is analogous to PyQt/PySide and wxPython, the Python wrappers for Qt and wxWidgets, respectively. Its original author is GNOME developer James Henstridge. There are six people in the core development team, with various other people who have submitted patches and bug reports. PyGTK has been selected as the environment of choice for applications running on One Laptop Per Child systems.

wxPython is a wrapper for the cross-platform GUI API (often referred to as a "toolkit") wxWidgets (which is written in C++) for the Python programming language. It is one of the alternatives to Tkinter. It is implemented as a Python extension module (native code).

Fast Light Toolkit (FLTK) is a cross-platform widget (graphical control element) library for graphical user interfaces (GUIs), developed by Bill Spitzak and others. Made to accommodate 3D graphics programming, it has an interface to OpenGL, but it is also suitable for general GUI programming.

PHP-GTK is a set of language bindings for the programming language PHP which allow GTK graphical user interface (GUI) applications to be written in PHP. PHP-GTK provides an object-oriented programming interface to GTK classes and functions. PHP-GTK partly supports GTK2, but GTK3 is unsupported.

PySide is a Python binding of the cross-platform GUI toolkit Qt developed by The Qt Company, as part of the Qt for Python project. It is one of the alternatives to the standard library package Tkinter. Like Qt, PySide is free software. PySide supports Linux/X11, macOS, and Microsoft Windows. The project can also be cross compiled to embedded systems like Raspberry Pi, and Android devices.

U++, formally known as Ultimate++ - is a C++ RAD framework that aims to reduce the code complexity of typical desktop applications by including all necessary toolkits into a single C++ framework. Programs created with U++ work on multiple Operating Systems and Hardware Architectures with performance without needing to write platform-specific code.

LessTif is a defunct free software reimplementation or clone of the Motif computer programming toolkit. The project aimed for full source- and binary-code compatibility with Motif. While this was not achieved, many Motif applications could run with LessTif or be compiled with it.

SunView (Sun Visual/Integrated Environment for Workstations) is a discontinued user interface toolkit and windowing system from Sun Microsystems, launched in 1985, and included as part of its Unix implementation, starting with SunOS Release 3.0. Sun had introduced support in 1983 for a window-based environment known as the Sun Window System, providing the Sunwindows (or SunWindows) window manager and Suntools (or SunTools) user interface toolkit.
