If you really want to be really good, don't learn how to read music if you're leaning to play guitar. Find tabs how to play the basic chords and the basic pentatonic scale, and then take it by ear.
However, if you just want to learn the basics to jam out in your bedroom, get Guitar Pro. Its a program that you can download song files and it shows you how to play them with no reading required. You can slow em down to play along and all that ****.
However, people who learn how to play this way are those guys who sit at guitar center all weekend playing Master of Puppets front to back, but have never written a piece of music in their lives. It's like paint by numbers.
