Sorry for being slow to reply, I was travelling this week end.

:). I think you should try to learn a bit what a dictionnary is in
Python, and understand the concept of namespace to do these things, but
anyhow, I'll try to help you right away. I don't have the code installed
on this computer, so I'll just try and modify your code. I can't garanty
that the resulting code will actually run :).
# Some class here...
self.member = "SOMETHING"
# Some function here...
instance.member = "SOMETHINGELSE"
# Main program
if __name__ == "__main__":
from IPython.frontend.wx.wx_frontend import WxController
from IPython.kernel.core.interpreter import Interpreter
# This variable should be accessible from the shell below
testinstance = Testclass()
# Here is a dictionnary which will be the namespace in which our shell
# runs. We bind the variables we are interested in accessing in it.
namespace = dict()
namespace['testinstance'] = testinstance
namespace['Testfunc'] = Testfunc
interp = Interpreter(user_ns=namespace)
# Generate frame
app = wx.PySimpleApp()
frame = wx.Frame(None, wx.ID_ANY)
# Generate shell child
shell = WxController(frame, wx.ID_ANY, shell=interp)
