Need help with mounting guns using Blender

So I'm really confused about mounting objects in Blender. Would I have to create the mount points in Blender for this to work? If so, I really have no clue on how to do this. So would you have to create a mount point on the back (unused weapon), a mount point on the hand (using weapon), and a mount point on the gun (so the hand knows where to mount too? Or is this all done using TorqueScript? I'm extremely lost on this. Are there any tutorials on this?
