This becomes a local var, i.e. local to __init__. To make it an instance var
write
self.text = wx.StaticText(panel, -1, 'Click results')

Re: wxPython: Should you use a master sizer object?
IIRC the wx dox contain stuff about sizers too. It's definitly worth to get into this stuff. Once you are used to sizers, you don't want to miss them anymore.

You must not access wx from more than one thread. Read their wiki about this and about the appropriate workaround. Morpheus -- http://mail.python.org/mailman/listinfo/python-list
What am I supposed to do with an egg?!
On Windows I'm used to install packages by setup.py install. So did I with Fibranet nanothreads - a few seconds and it was installed. On Linux (ubuntu 6.06) all I could get at is an egg file. I found out that I have to exec easy_install, which didn't much help here (seems to me, at least - sorry, Linux newbie). So, what am I supposed to do here now?

Consider using sizers, you'll need them anyway. They do such things for you, and many other things too. The help file has a good chapter on this: Working with sizers.
