I"
ve always felt that:

1) slavishly following MVC is pretty pointless

2) to the extent you do follow it, it's very application-specific, so
I"ve never quite understood what an out-of-the-box MVC framework would
look like.

3) You can certainly do it with wx.

there is the XRC format, but when looking at it, it looks like it jsut
 makes things more complicated -- decoupling strictly GUI code and
belongs-with-the-GUI code seems pointless to me. And I really like
code-generated GUI layout. I suspect that that approach makes much
more sense with C++ than Python.

I haven't used signals and slots, but I agree that wx events are bit
stifling. A number of folks recommend pubsub for a more de-coupled
approach.

Well, wx definately doesn't get as much attention on the Mac -- I've
seen more issues there. Maybe QT gets more love -- what with KDE and
all, it probably has a significantly larger user/developer base.
