I doubt it -- at least not with raster data. A while back wx's vector 
drawing was pretty limited (no alpha support), but it now has a better 
drawing API, or you can use it with Agg or Cairo, or?? There may well be 
other reasons to choose QT, but I doubt they are specific to Geospatial 
applications.

As a matter of fact, as much as I like QGIS, I think it would work 
better if it were written in wx, at least on teh MAc -- for example, teh 
file open dialog sucks -- with wx, it would use the native one, which 
would be much better.

It doesn't use Tk, it uses GTK, but your point is the same.

SAGA had promise, but it seems to be kind of stalled.
