Sometimes silence and just trying to not do anything that would lead them on is the only good option. Clingy people in general can be annoying, but it is something everybody has to deal with at one time or another. Just be polite and say hi if she says hi, but keep your distance as well. Treat them only as an acquaintance and nothing more. You were frank with the girl, so you did your part, so you don't have to worry about it anymore.
It gets really annoying when they try to take it to a higher level by not respecting your personal space -- that just gets creepy, but again, you can just be polite and then just get up and walk away. Sometimes there is no way to get out of the situation except by not even associating with them, but in a lot of cases that can't happen. Stick it out. It is a "crush" and they will eventually get over it.
**EDIT**
I had this one girl who had a crush on me in High School, but I was not interested. She was very, very clingy too, which was annoying. I go off to college and after I graduate, I see her again because we had mutual High School friends. I thought she got over me, but apparently she hadn't (which is a little scary after that many years to be honest). The last time I saw her, she happened to be at the same bar as me when I went to hang out with a few friends. I was sitting there talking to my friends, and she comes up and starts talking to me. I was civil and friendly, but nothing more. She starts to get really touchy and basically rubbing up against me which if she knew me at all I would not appreciate. It was not a pleasent experience. I basically ignored it and kept talking to my friends and drinking, but man, that was a little creepy. I figured if her antics innitiated any response at all, it would just spur her on. She is a nice girl, but dude, respect the space.
She eventually walked away, but man, you would think after 5 years of not seeing someone, they would be over it by then. <shudders>
