Smoothing CDF or survival functions are not quite the same as usual scatterplot smoothing, at least because of the monotonicity contraint. I don't know of kernel methods for smoothing such functions, but I believe people have used splines. I'm no expert though. It's best for you to consult an expert or search the literature.
