Wolf like me ...it's the only song I ever tried to learn on gutiar and I could kinda play it at the time...the person trying to teach me and I almost became enemies because I get frustrated when I'm not good at something staight away. But I pick that song then cos even I learned it !!! For a night anyway :p
Try searching a song you like on songsterr.com
They use a tab player to play out each tab of a song making much easier to learn and get your finger posistioning correct. Nirvana would be a good starting point.
