You need to explain what GUI you are using, and also what you mean by 
'more than one process at the same time'.  If what you mean is 'when
I click on each button I launch a separate program' then you are
building a launcher (and Mark Lutz, Programming Python second edition has code
that does exactly that using Tkinter which you might be interested
in.  The CD that comes with the book has the code.)

If you mean, 'while I am running my application, I want my users
to be able to interrupt things by clicking on buttons' then you need
to thread your application.  The best way to communicate between
threads is using a Queue object, and

will show you how to do that.
