Evan,

I tried Derek's suggestion about making an array of captionless windows, but
found that I couldn't make the black keys in their proper positions,
"overlaying" portions of the white keys;  I tried buttons, too, with same
problem.  I then tried making a drawing of a piano keyboard, with the
intention of saving each key as a separate .bmp, and then pasting them onto
the screen so they looked like one keyboard, but as I was doing that it
finally dawned on me that it would actually be simpler to just...test
against x-y position of mouse!!

So my inexpert conclusion is that isn't really a useful easier way than what
you were already aware of.
