Hi Gene
Why not up to speed with Eagle, albeit a horrible package. This has all
been done !
The free version of eagle should suffice. There is an automatic g-code
generator. Thats the best part. And some guys have written apps to probe
the board prior to milling, to correct for undulations.

I started with cyanoacrylate, which is stiff, but
there is actually mounting wax that is made for this purpose. Its a hard
wax that melts at about 200F. I have used it to mount non-ferrous metals
to a steel fixture for surface grinding. We have also used it to mount
glass for cylindrical grinding. If needed, it cleans up with acetone.
