Yes, this seems to be confusing a lot of people. I want to be able to
use various existing plotting libraries (most of which use wxPython or
pyOpenGL). The end result is that (assuming my paths etc have been
correctly set), I can type something like this in my console:

Simple. its because my main application (the GUI that is), is written in
VB6. I have a MDI application (i.e. many child windows in the same
application), and I want to use one of these windows as a console to
inteactively type Python commands. If I were to use wxPython, I would
not be able to treat the console 'the same' as the other child windows
in the application (i.e. minimize, close all etc). Maybe a simpler way
to think of this is to imagine that I am writing a PythonWin clone in
VB6. What I am asking here, is how can I create the 'Interactive Window' ?
