(Modular-)Application Framework / Rich-Client-Platform in Python

[Wildemar Wildenburger]

To make it short: Is there something like this already?

There seem to loads of python frameworks for Web-Apps, but I have a hard 
time finding one for desktop-apps.
I imagine it wouldn't be too hard (if still time consuming) whipping up 
something simple myself, but I thought, I'd ask here before diving into it.
