Aww, you don't need the guts to tell her if you're truly serious. You can just ask her if you'd like to have lunch with her or just hang out together for a little bit. Go see a movie, go to the library, or maybe even just talk together! I'm pretty sure that once she gets to be around you a little more she'll be more likely to say yes. You also may gain your courage once you see if she's really perfect to you. Take your time with her! I'm not sure about her, but I like taking relationships slow. So take the time to be around with her more; you two might warm up to each other. Then you could realize that you can take your relationship to the next step. ^^
It may be a little uncomfortable to even think of asking your friend out, so I suggest beginning with not actually a date, but some time to hang out together.

It's so sad that I check back on this thread regularely, lol.
