I believe it should be doable with a recent X server and a normal compositing WM. The XShape extension -- on recent servers -- can clip input regions only, letting events be delivered to the underlying windows below.
A sample program is attached. If your X is recent enough, it should give you a fully opaque window with a 100x100 square in the middle that's transparent to events.
For briefness, I don't do any error checking.
