Need some help smoothing two spheres

Hello,

I am new to nurbs based modeling and am already interested in making a complex shape. Essentially I would like to know if there is a simple way to smooth 2 spheres and a plane. I have tried the blend tool and all by itself that doesn't seem to generate the results I need. I also have tried to use Network after building up some silhouette of the spheres but that didn't work either (and in some cases made some very bizarre shapes). Same with loft and sweep. I am wondering if perhaps the only way to build this will be to build it manually with curves?

Can someone take a stab at an easy way to smooth these 2 spheres? Keeping the smoothed surface tangential to the sphere surface and still have it be easy to modify in the future would be preferable.

Thanks,
Chris
