touchscreen

I was told that any monitor could be turned into a touch screen if you have the right software. This has got to be old news, or even a myth. Please shed some light on this if you can. Am I wrong?

My primary question is which cable would normally be used to hook up a touch screen. Would you need 2 cables for this (one for the monitor, one to receive touch events?), or is a single cable going to have data in both directions (perhaps an HDMI?)
