Hi Glyph,

I have 3 versions of my code, one using wxreactor, one where the 
mainloop is wx's and Twisted's reactor is in a thread, and one where 
it's Twisted's reactor as the mainloop and wx is in a thread.

To answer your question, originally I considered pyQT but when I saw 
that it wasn't free I changed my mind. pyGTK, the problem is the 
integration in different OSes, I need great integration in Linux, Mac OS 
X and Windows and  GTK apps don't do that as well.

Yes, that is what I ended up doing :-)

Cheers,
Gabriel
