That's more than a one-liner.  8-)

The Wiki page at http://wiki.wxpython.org/index.cgi/LongRunningTasks talks
about this kind of problem at length, and includes a couple of alternatives
to using threads.

When using threading in a GUI, the number one rule is that only the main
thread can access the GUI.  Worker threads that want to update the GUI must
do so by posting events to the main thread.  The way a typical wxPython
program does this is by defining its own event class and using wxPostEvent
to post instances of that event class to the main thread.
