We want to control the iTunes information on one computer from another area in the building so that the songs play over the speakers connected to that computer, can we do that?

We are a church that uses iTunes for the background music and the leaders would like to be able to control the progression of songs, etc. from up front instead of back at the sound booth. We don't want control of the tv screens just the music that comes through the speakers/sound booth attached to the computer. Can we attach apple tv to the computer with some sort of converter and then be able to control what goes on in iTunes and since the computer is hooked up to the sound system have it play through?
