scale with ffd 2x2x2

I tried to do it myself...

I tried to do it myself... :-(
I have some problems :
- It works just with meshes : I can't manage to add fdd mofifier to groups, meshes and subobjects..
(I can do by hand but not with my script knowledge)
- It is a "inprogress" script so it can just change one axis when running script but I don't know how to close the window when click button.
Can somebody help ? Thanks.
