How do I get a guy I barley know to sorta like me, even just friends would be nice?

I remember this new kid who started off at my school awhile back,
he transferred from the local private school so I sorta knew him but not quite
I asked around to see what his interests were and starting talking to him and getting to know basics on facebook/myspace and such
Lets say this guy plays guitar or something, You can respond with something like "Wow, I tried to learn but I was horrible at it, how long've you played?"
This will flatter him without being to forward

Or if this guy isn't new and you've known him for awhile but just haven't talked to him,
see if you can get a chance when he's alone and say "Oh, you know, I haven't really ever talked to you but you seem chill and I think we should get to know eachother. I've seen you hanging around with my friend."
You get the point
Just bring up a really relaxed subject to talk about and work it up from there
He'll like how easy going you are but don't be TOO obnoxious because that always gets guys annoyed.

Just be yourself if people can't accept you for who you are then you don't need them. Go up and start talking to him, maybe sit with him at lunch to get to know him better, text him, or ask him to do something with you on the weekends. Just take it slow and don't force/push him. You don't want to scare him off. Just be friendly and get to know him. Ask him to go eat or a movie or something and bring some friends if you think it is too awkward and you don't want him to think it's a date or something. Talk to him about a hobby or something that interests him.
