Guile-gtk is a library written to make GTK 1.2 accessible from guile. It provides a convenient interface for Scheme programmers to develop visual applications. It can also integrate with GNOME via the Gnome-guile module. (For glib2, see guile-gobject instead.) Guile-gtk was started by Marius Vollmer and is currently maintained by Ariel Rios and other intrepid Guile hackers around the world. Guile-gtk is free software licensed under the GPL.
