Dear Tim:
by the way, quick question, do you know of a way to "get" the extended
style bits? I haven't been able to find anything on MSDN. In other
words, if I do as you suggest below for a few windows, how can I query
those windows again to see if those bits that I previously set using
SetWindowLong() are indeed set?
Thanks!

I'll assume you already know how to find the window handle of your
victim window.
The key concept is that you need to set the WS_EX_LAYERED bit in the
extended styles, then set the transparency level using
SetLayeredWindowAttributes. You can look up both APIs in MSDN for more
detailed information.
import win32gui
import win32con
win32gui.SetWindowLong(handle, win32con.GWL_EXSTYLE,
win32con.WS_EX_LAYERED)
win32gui.SetLayeredWindowAttributes(handle, 0, 128, win32con.LWA_ALPHA)
