GLUT -> another GUI

Hi,

Again a little problem. I have set up a nice object viewer with clicking abilities etc etc in GLUT. Further this program loads obj files and renders the triangles.

I wanted to add to my GLUT application some more options. I was thinking of FOX. But when I looked at the documentation I could not find how I should render my loaded objects? There are only kind of Trianglemeshes? I actually don’t know how I should render these triangles? Is there a other way to fulfill this task?
I would very appreciate if you could help me solving this problem… I would be very happy if you could give me further advice which GUI would be nice and wise to choose for an image processing application ???

Thx.
