When I was first interested in playing guitar I used Musicnotes.com free Guitar Guru which gave you a little sniblet of a song you wanted to play, they had a digital guitar neck and showed you where to put your fingers, once you get to know the chords, just type in the name of the song you want with chords after it in google, usually takes you to ultimate guitar chords .com
That's where I learn my songs from now.
Guitar guru is awesome for beginners though and has plenty of songs that you will know and samples are free for every song they have. You need to download the Musicnotes Suite in Free Stuff.
