It seams like they switched to qt. I know it is possible to find a lot
of references on the web where wx, qt, gtk, even Tcl/TK are compared.
But I am wondering if there is some Geospatial reason to pick qt instead
of wx.

wxPython is awesome. I wich they where around 10 years when I used
Tcl/TK on a project, a diagram editor for map algebra. That project
could be alive until today. :(

Some time I wish that OpenEv could use wxPython instead of python+TK. I
like OpenEv and I use it a lot, but it is hard to introduce it to end
users. "wx" produce much better results in term of adapting to the look
and feel of the hosting platform than Tk.

I completely agree with Chris.
