That is something I would use just about every time I use the Gimp. See  
this bug report in which I roughly sketched out how I'd use such a  
thing (i've refined it in my own program a little, but it's basically  
the same). It calls for a three point transform defining an affine  
transformation:

I personally wouldn't mind seeing some such tool completely replacing  
the separate rotate/scale/shear tools. I started to develop such a  
tool, but I keep getting sidetracked..

Also see this bug report about adding a "free transform" tool:
http://bugzilla.gnome.org/show_bug.cgi?id=138462

I've also been (very, very) slowly making a tool to stretch around  
images using some form of bezier patch within the Gimp, which is  
relevant for the following bug report. Too many other projects getting  
in the way!:
