Yes, you can. There are two possiblities, the one is converting the 
toplevel into a frame with wm_forget(), after which you can simply pack 
it into another frame. The second one is configuring a frame as a 
container, which allows to even embed a window from a foreign 
application. I'm not sure this works on all platforms, though.
