In my view, you should have a window structure of your own, which among 
other things points to the Gtk window. Then you just have to get the top 
window origin and dimensions and create the task dialog with the same 
geometry, save the pointers you need in your window structure, etc...

Incidentally, if you want to have multiple top windows then this window 
structure is the data pointer that you should pass in g_signal_connect 
functions, because this way you are automatically on the active top 
window everytime the user does something!
