Well, there are a bunch on YouTube and Vimeo, but most are for modelers like Hexagon or Blender where the techniques use other tools than just box modeling (which is all Wings really does). What I do normally is start with a cube, cut it in half and then create a virtual mirror so that I only need to do one side of it ;). From there, it's just a matter of pushing verts around and creating edge loops :).

Have you looked at Blender? Up until 2.5 I would never even touch it, but now that the interface is usable, and given the plethora of information and tutorials available for it, it might be a good choice for you.
