I'm trying to add drop shadow to my in-game windowing system, by creating the gradient drop shadow by hand in photoshop and then drawing it beneath the graphical window. The problem is I can't figure out the proper opengl blending function, any suggestions?

Have you tried multiply? That should be zero and source color, respectively.
