Because there seemed to be more interest in Qt I had left temporarily 
left the GTK project I was working on. I will still get back to it at 
some point. I had originally chosen GTK becuase it was based in C which 
I thought would mesh better with GRASS. Also, I have almost no 
experience with C++.

To recap what I had done was to essentially build a GTK GRASS monitor 
surrounded by a UI. I took the existing display device code and built 
the GTK stuff around that. The GUI then also acts as a device which can 
recieve GRASS commands from outside of the UI. The whole thing was put 
together as a GLADE ( http://glade.gnome.org/ ) project.
