Looking for suggestions for a desktop rich GUI
dkersten: I personally use Qt for my GUI needs and am building a large startup-related app with it at the moment. If working in C++ is too painful/slow/effort for you, PyQt is a powerful (and very easy) alternative, but the license may not suit your needs (dual licence GPL/Commercial). PySide is an LGPL version thats compatible (or almost compatible) with PyQt, developed by the Maemo team, but I'm not sure how mature it is.Qt has excellent support for traditional GUI widgets, graphics (you can even embed widgets in OpenGL, allowing you to transform, zoom, rotate etc them as OpenGL geometry), networking, concurrency, plugins and other niceties.
