Given a set of guitar chords, I want to know how I can determine what key a song is in.

For example, if I play a song using the chords C - D - G, how can I figure out what key I'm playing in? What if I play Am - G - C - F? Or any other set of chords that sound good together? Is there a trick or calculation that will give me the answer? Does it get harder if I'm using sevenths, minors, ninths, or whatever else?
