Two of my dear friends are having this debate: Can Guys and Girls ever be Just Friends?
My two cents:
I think that if you are friends with a person, male or female, there is something about them you are attracted to. If that element of what attracts you to them disappears, the friendship probably will as well.
Most often in opposite gender relationships, there is romantic inclination/expectation on one part or the other, not both. (That is where I am usually the big sucker, but anyway...)
Guys and girls can most definitely be friends as long as an element of expectation is made clear. If one of you establishes you will never date, then you can move past that "awkward moment," evaluate if whatever initially attracted you is enough foundation for a lasting friendship, and make the best of what you have to offer each other.
