I started playing guitar 12 years ago. As many have suggested here, pick some songs you like and learn to play them. This keeps you motivated. If you just learn chords and have no way to put them together you will get bored fast.
Here are a few songs that could get you started:
Pearl Jam - Last Kiss (Originally recorded by J. Frank Wilson and the Cavaliers):
G-Em-C-D
Same four chords for the entire song.
Bob Dylan - Knockin on Heavens Door:
G-D-Am
G-D-C
If you're a Dylan fan his early albums are a good place to start. Most of the songs are very simple.
Then of course, you must learn as many Beatles songs as possible.
I have to warn you though. When you first start playing it's awkward as hell. It can get very frustrating at times. But once you get a few of the basic chords down you will progress fast. As they say, the guitar is easy to learn but hard to master.
