What is GTK+
GTK+ is a multi-platform toolkit for creating graphical user interfaces.
Offering a comprehensive set of widgets as well as facilities for creating
your own widgets, GTK+ is suitable for projects ranging from small one-off
tools to complete application suites.
GTK+ has been designed from the ground up to support a range of languages,
(especially in combination with gobject-introspection and the Glade GUI builder)
provides an effective method of rapid application development.
GTK+ is free software and part of the GNU Project. However, the licensing terms
for GTK+, the GNU LGPL, allow it to be used by all developers, including those
developing proprietary software, without any license fees or royalties.
Since its origins as the toolkit for the GNU Image Manipulation Program (GIMP),
GTK+ has been used in a wide range of software. Notably, GTK+ is the foundation
of the GNOME desktop.
