Year 7 girl really cute, I'm in year 9.?

I'm a 14 year old guy in year 9 this year (Turning 15 in 3 months) and I've seen this girl in year 7 at recess and lunch at school, I don't know her personally and I haven't even heard her voice or spoken to her.
She always hangs around with one girl, her best friend I assume. The girl I'm talking about is really cute and seems shy. I just don't know how to go about talking to her and getting close to her, it'd be really awkward.

None of my friends know that I feel this way. You may just be thinking I want her for her looks, but I don't.
I think many girls my age looks 'hot' I guess you could say, but this feels different than just looking at someone and thinking they're hot.

The first time I seen her was in March or so this year, when I was in my plastics class (Elective I chose at school) and she was in Technology (Only class the Year 7s have in the Tech rooms). I noticed her when I was using the drills and she was staring at me through the window between the classrooms.
She stared at me heaps, my mates and I realised and I thought nothing of it, we made a bit of a joke out of it at the time, just for a laugh.
Another time my friends and I were sitting down outside at lunch time and the girl and her best friend walked past he she saw me and instantly went red and looked away.

So anyway, now you know the situation, What I'm asking of you guys (and girls?) is a nice way to go up and talk to the girl and her friend without it being extremely awkward and corny. By corny I mean something like going up to them and saying 'You're hot' or something stupid.
