For starters, you would need a modeling program such as Hexagon in which to make the mesh.
It can be rigged in D/S4.x.
For Legacy rigging, adding in morphs is a rather complex topic ... I would suggest looking for some tutorials and/or products to help you do what you're wanting to.
Making clothing for Genesis is a LOT easier as so many of the morphs come naturally into the clothing for us.
