Doing it manually is actually pretty easy because of how Wings works: just select two opposing edges and hit C to divide the face between them. Still, if that is really too hard for you just select the face you want to subdivide and hit S for smoothing.
Hm, I suppose the connecting edges thing I mentioned is just tesselating the mesh. Whatever, you can subdivide a polygon selection (including just a single polygon) as I described: select the polygon(s) and hit S.
