This tutorial describes the Ruby interface to GTK. There are GTK bindings for many other languages including C, C++, Guile, Perl, Python, TOM, Ada95, Objective C, Free Pascal, Eiffel, Java and C#. If you intend to use another language's bindings to GTK, look at that binding's documentation.
For the latest information you should look at the C bindings tutorial for GTK. It can be found at http://www.gtk.org/.
