os.kill for win32

[grant]

Anyone know the same functionality of the os.kill module for the win32
platform.  All examples that I've seen are just for Unix.  In the program
that I've written I'm lauching an external program via a wxCheckbox
switch and would like to kill the program when the switch is unchecked
however wxKill only works on Unix, and os.kill is the same.  Is there any
relatively simple way to do this same thing on win32 (NT platform)

Thanks
