You can try to use Twisted's wxPython integration support:

But note the warnings about how well it is likely to work.  Using a separate
thread might be the best solution.

I'm not sure what you mean.  The data is available in the `received' attribute
of the protocol instance.  Any code which needs to manipulate the data can get
that list and do whatever it likes with it.

I intentionally added code which shuts the server off after the first round
of connections is completed, since that seemed to be what your example
program was doing.  If you don't want this, just remove the shutdown code.
