How can i learn to play guitar without lessons?

i’m 17 years old and i want to learn how to play the guitar, but i don’t really have the time to take lessons…i saw a commercial on tv for the "i can play guitar" game for kids. i’d be really interested in something like that but i don’t know if it’s too small…i read that it was specially made for children’s hands…
anyways…please help.

Can you learn to play guitar without having ever held one?

When I was young, some of my friends knew how to play the guitar really good and I alwawys wanted to learn. I always wanted to play the guittar, the piano and violin, but first of all the guitar. Is it possible to learn how to play guitar without having ever held one. If so, how and is there a website to go to or what.
