uwave control panels are pretty simple - usually just some buttons, a display, maybe a rotary controller, and an embedded controller IC.
But you really do not want to be experimenting with custom control unless you know exactly what you're doing. Aside from the risk of nuking food and/or accidentally bypassing the door switch and microwaving yourself/partner/kids/pets/etc, most uwaves have huge power capacitors near the controller board.
An unplanned encounter with one of those can kill you.
Here's a sample circuit. It's not super-complex. But there's a lot to go wrong, and it's really not a beginner project.
Remotes are basically the same with (usually) an IR transmitter, more buttons, and no dangerous power switching. It's not all that hard to clone one, but the hard part is making the tiny physical buttons and inventing a better UI.
