Be friendly. Smile. Not a creepy-smile, but just a natural smile. Don't force it. If you really can't smile without it looking forced, just practice by saying "yes" and letting your cheeks lift up. This doesn't tell girls "hey, I'm interested in you," but it tells them that you're friendly, and it will make them want to talk to you more.
Talk. So many people poke, flirt, "hit-on" women without ever attempting to actually talk to them. Now, obviously, if you're simply looking to get laid, there are different ways to approach it, but since you're asking about girlfriends, I'll ignore that.
So, yes. Talking. Since you asked earlier in the thread, "and then what?", I feel that you might need a little more direction in this regard. Talking involves listening, and speaking. With women in particular, you should often be doing more of the first (if you can get someone talking about themselves, you will come off as an incredibly good conversationalist, even if you don't say very much about yourself).
Ask questions. Questions keep a conversation going, and will get the girl talking about herself. Now, that doesn't mean a conversation should go like this:
Guy: "Hey, what's up?"
Girl: "Oh, not much."
Guy: "What do you mean?"
Girl: "Uh...not much?"
Guy: "Oh, okay: so what's your name?"
That'll come off as creepy, and desperate (or fumblingly cute, depending on the girl, but that's less likely). While questions keep a conversation going, they do not make for conversation in themselves. Completely random questions don't work, unless you've been talking for a while and something is just on your mind.
Guy: "Hey, what's up?"
Girl: "Oh, not much."
Guy: "Haha oh come on, /something's/ gotta be happenin'."
Girl: "No, really, I'm just bored, haha."
Guy: "Haha dang, am I really that boring?"
etc.
Don't force trying to be funny if nothing comes to mind. More importantly, when you ask a girl a question, listen to her answer. Don't blow it off. Look at her (don't stare, just pay attention), don't text while she's talking, let your body language tell her you're listening (nod your head when she's saying something, etc.).
Other than that, just be yourself. Getting a girl to notice you and to want to be with you isn't worth anything if you have to pretend. Talk. Laugh. Smile. Be yourself.
That being said, once you're starting to really talk to a girl, don't be afraid to ask her on a date (don't call it a date; just ask if she'd like to see a movie or something). Just because she says yes doesn't mean you're dating, and don't rush anything. Don't stop moving forward, but don't jump from first date to trying to kiss her, as she might still be in the "talking" stage.
Good luck.
