There's nothing hard about threading, really.

Code below is not intended to actually work, it is just pseudo-code which I
typed in my mail editor, but should show you the idea.

---- pseudo-code starts ----
from threading import Thread
import wx

# ... Make your progress-bar, WX windows, etc
def init_wx_ap():
pass

def a_method(prog_bar, arg1, arg2):
do_some_work()
wx.CallAfter(prog_bar, value1)
do_some_work()
wx.CallAfter(prog_bar, value2)
do_more_work()
wx.CallAfter(prog_bar, value3)
return

t = Thread(target=a_method, args=(my_prog_bar, arg1, arg2))
t.start()

---- pseudo-code ended ----

This is a good wiki entry on the subject:
http://wiki.wxpython.org/LongRunningTasks

I've used the techniques there and I've messed with the delayed result
one in the demo. Both are good places to start. You could also read up
on the docs for the thread modules.
