I don't think you have to make it the active window - you just need the
Window ID which is most easily obtained that way.  Sorry about the URL
Above being a bit sketchy, it was more personal notes than a comprehensive
description of xdotool (which is beyond my knowledge), but I believe
it should be possible to achieve what you want using xdotool.

You could even run a virtual framebuffer instance of X11, in which you
launch your target application, establish it's window ID, then send
events.
 
I'm sure there are more elegant solutions, but this one is workable
if extremely inefficient/hacky :)
