First, you have to decide which GUI toolkit you want to use. Here's an example Google found using Tkinter http://code.activestate.com/recipes/124894/

Linux counter #99383

To run the stopwatch in the background, you need to check out the Python module threading.

May 'the Google' be with you!

I have made an alramclock with wxpython before with stopclock(countdown) as one of the function.
So wxpython has this function build in "wxStopWatch"
