GTK+ (GIMP Toolkit) is a cross-platform widget toolkit for creating graphical user interfaces. It is one of the most popular toolkits for the X Window System, along with FLTK and Qt.
GTK+ was initially created for the GNU Image Manipulation Program (GIMP), a faster graphics editor, in 1997 by Spencer Kimball and Peter Mattis, members of eXperimental Computing Facility (XCF) at University of California, Berkeley.
GTK+ is licensed under the LGPL free software license, which allows both free and proprietary software to use it. GTK+ is part of the GNU Project, which aims to create a whole free-software operating system (the LGPL was originally written for the GNU Project).
