I did some work on a set of GTK+ bindings.

Take a look at:

https://trac.ccs.neu.edu/trac/larceny/browser/trunk/larceny_src/lib/Standard/gtk.sch
https://trac.ccs.neu.edu/trac/larceny/browser/trunk/larceny_src/lib/Standard/gtk-2.4.sch
https://trac.ccs.neu.edu/trac/larceny/browser/trunk/larceny_src/lib/Standard/glib.sch
https://trac.ccs.neu.edu/trac/larceny/browser/trunk/larceny_src/lib/Standard/gdk.sch

and example uses of it in:

https://trac.ccs.neu.edu/trac/larceny/browser/experiments/gtk

Its nowhere near complete, but the fundamentals are there.  Some newer  
FFI features were added specifically to support the needs of GTK+;  
e.g. the establish-void*-subhierarchy! procedure.  Other bits were put  
in before I had developed define-c-info and friends, so there are some  
ugly hard-coded values that should be replaced with invocations of  
define-c-info or similar header importing macros.  Other elements of  
support were pretty much hacked in, such as the use of g_signal_query  
to dynamically extract the expected type of a callback in glib.sch.

Recently I've been experimenting more with OpenGL bindings than GTK+.   
But it would be good for someone with more GTK+ experience than myself  
to exercise the existing set of GTK+ bindings and add more functions  
to it.

A set of bindings for wxWindows might also be worth exploring.  PLT's  
system is based on a fork of an old version of wx; it would be  
interesting to see if we could hook into the current version of wx.   
But then again I do not know how actively that project is maintained;  
GTK+ seems like a safer bet in terms of long term support and activity  
from the development community.
