If you explain more closely *why* you need to do all this yourself,
and what customizations you need to do, it might be easier to find
something suitable for you. If you don't absolutly *have* to, why
build it all from scratch ?

With nothing else known, my personal tip would be to just
forget about it and get yourself one of the ready made
programmers out there (as a kit or ready built). Others
have already pointed out a few...
