No, you really can't. Wings 3D will only allow the most minor of edits to hair meshes (slight changes in length, using the Meshtool) and I wouldn't recommend it even for that as you cannot change bone assignments, and hair is highly dependent on exact and perfect bone assignments for proper animation.
There's no free program I know of that will let you do hair meshing, and, err, besides, $RaMRoM$, I've seen no evidence that you've successfully finished a body mesh - and that's a prerequisite before you work on hair. Basic stuff first, then complicated things like hair.
Milkshape is definitely worth the money to buy, quite nice to mesh in once you get the hang of it (especially for beginners) and is the only thing I know of (besides 3DS Max) that does Sims 2 hair in any decent capacity whatsoever. If you want to eventually do hair, after you have the needed basis and practice in bodies, you'll need Milkshape.
