You can use wxPython to do that. Or, alternatively, you can use the win32api
module from win32all (but doing it the win32api way is a major pain in the
ass).

wxPython less so ;-)

Here's some rough code for a biff-like IMAP mail checker I've once written
using wxPython (I mainly adapted the notify icon stuff from the wxPython demo):

This is not the easiest problem to solve, espeically for a newbie.

HTH,

Ugly code follows:

#!/bin/env python

from   wxPython.wx import *
import images

NOMAIL = 0
GOTMAIL = 1

class MainWindow(wxFrame):
    def __init__(self, parent, id, title):

        #icon = wxIconFromXPMData(images.getMondrianData())
        #self.SetIcon(icon)

        # setup a taskbar icon, and catch some events from it
        icon = wxIcon("normal.ico", wxBITMAP_TYPE_ICO)
        self.tbicon = wxTaskBarIcon()
