I don't understand what you mean by unweighted and weighted here. 
Nonparametric regression is, in my understanding, aleays some kind of
weighted local combination of response given predictor: that is the
whole point of the exercise. 

Otherwise, yes: in Stata 10 this sounds like -lpoly- (formerly
-locpoly-) with -kernel(rectangle)-.

I would like to get a prediction from  unweighted
uniform kernel smoother. In STATA, it seems "locpoly"
is the one to do this kind of nonparametric
regression, but it gets weighted conditional mean. I
was wandering whether there is any syntax in STATA
which could be used to get unweighted conditional
mean. Or I might understand "locpoly" wrong?
