I've used wxpython a lot in the past, and maintain some code that uses it
and I do like it, there are a couple of bits that have put me off though.
There doesn't seem to be an obvious way to implement an MVC type pattern
with it. I haven't used Qt much at all yet but QML looks extremely
interesting and pretty powerful. This signal and slots in qt reminds me a
lot of the outlet actions in the iOS world as well which helps a lot at
keeping everything de-coupled. I've found an awful lot of bugs with wx over
the time I've been using it as well which has put me off somewhat, but
that's probably true for a lot of systems/frameworks of that size that you
get very familiar with and use a lot.

Do you know any Qt apps for mac? It would be quite useful to take a look at
a few to help weigh up my options.
