What GUI toolkit are you using? I know that wxPython has a status widget that could be updated in a thread and it has some good examples of using threads with long running tasks. I created a program with it that deletes folders and updates me on its progress. You can see the wxPython implementation here: http://wiki.wxpython.org/LongRunningTasks Their widget is called a ProgressDialog. I think there's a custom one too...
