So far I've used Python with Tkinter, and a touch of PIL. I'm pretty

OK, then dig around in the Tk docs and examples you can find.
In any case, what I'm suggesting is that you don't need any fancy
transparency in PIL -- you simply draw your image onto the screen
(probaly add it to the Tk Canvas), then you draw your circle with the
cross-hair on top of it, using Tk -- you aren't changing your image, so
you can get it back by re-drawing it, or just removing the cross hair.
