This one, at least, is fairly easy. Just design your own window (or pinch the
standard one), open it, and then enter a minimal polling loop. The only
messages you *have* to respond to are mouse-click (on the OK/cancel buttons)
and message-quit. It's probably a good idea to pop up a greyed-out menu if the
user requests it, otherwise it'll look as though your application is broken,
and you probably want to respond to open-window, otherwise the window won't
move. You also need key-press if you want to allow escape to terminate.

  It actually took me a while to realise that you can have more than one
polling loop in a program - obvious in retrospect, of course. I don't think
I've ever seen it suggested in a magazine article, though.
