[Image-SIG] GUI Toolkit recommendations

[Chris Finley]

Greetings,

I'm new to Python and GUI programming (from the Perl/Web world) and
would like some recommendations for GUI toolkits or reference to toolkit
reviews. I'm presently looking at Glade, but that is more by
happenstance than purpose.

The application is a CAD program for testing and manipulating
signed-distance field models. The SDF models will be created from
functions or converted from polygon meshes.

I'm programming more of a research tool than end-product, so the desired
traits are:
1. cross-platform compatibility
2. easy to use and quick development
3. professional looking

Your advise is greatly appreciated,

Chris
