You can get cheap USB IR receivers specifically made for capturing the IR "codes" of remote controls for adding to third party remote control systems.

I've used them at work in the past for setting up touch panels, etc. to control older equipment like DVD players and TV displays. Point remote at IR receiver, push "power" button on remote, record the string for "power on", then program your control surface to send that same set of pulses via IR emitter when you push the software button for "power on" on the touch screen.

You can build something like this as well:

I have a Casio CMD-30 that can ‘learn’ codes; its a fun watch.
