How should I approach her? Everyone says that I should just walk up and say "Hi", but since I'm a shy guy and I'm not that type of person, I think it would make it way too obvious that I like her, and I'm afraid that it would freak her out and make everything awkward.
Everyone is right. Think about it logically, how would saying hi make it obvious that you like her? It would make it obvious that you wanted to talk to her, but that's all. Why not just say to her at her locker, "Hi. I am _____. I just wanted to introduce myself since we seem to see each other around a lot," and just take it from there. She is just a girl. She breathes the same air you do. Don't make her out to be some goddess that you can't look in the eye. Confidence in yourself is the key. Girls love that.
So, how can I approach her and talk to her and hopefully turn it into a relationship in the future?
Whoa there a second... You haven't even talked to her but you are hoping to have a relationship with her in the future? You may not even like this girl. It is that type of unrealistic thinking that may freak her out and which keeps you from talking to her. Dial it back some. Baby steps. All you want to do right now is talk to her. So do that. And go from there.
Good luck.
