I'm personally more interested in the Mozilla platform (XUL) because I prefer writing UI using a markup based HTML type mechanism. But I think this would probably be a lot more work than what you really need.
I believe that both Qt and wxWidgets have an OpenGL window mechanism included with them, so probably either one would be a pretty good fit.
I'm not really familiar with what UI libraries are available that would render themselves using OpenGL.. I would worry that you probably won't find something quite as general purpose or as stabilized as either one of these.
It will be fun to see what new stuff you cook up for topmod!
wow. these links are great. thanks so much for your help. i'll keep you updated on what we do with topmod. I did finally get a new version compiled for windows in mingw, but the code for the new functions is still being debugged. I will post it here when I get a stable version of the code from the students who are working on it in the lab...
