What is the Optimal GUI?

[cpb]

Hello,

I am looking for an optimal GUI for developping a OpenGL 3D Viewer AND a image processing program that enables drawing on eg. bmp images (like drawing a polygon or a box etc.. nothing fancy)...

what would be an optimal development environment???

Thx for your help.

chris.
