Which IDE is recommended?

[Matt]

The ActiveGrid IDE is a sample app with wxPython. It has a lot of good
features including a source code debugger that allows you to debug wx
apps and set breakpoints from the code editor. I am also biased
though--I work on that IDE and use it for all my coding. Its pretty far
along on Windows and getting better on Linux. We just got it working on
a Mac yesterday so that version won't be out for a bit.
