Why open windows at all if you do not intend to actually show the customer 
anything until you are done?

I simply open a status window at the start that shows how far the process has 
gone, not pop up any windows at all during processing, and inform the user of 
success or failure when the process is done - after that the user can decide 
to view all the data at their leisure.

Another technique that I've used is to create tabs in an already open window 
instead of creating more windows. Adding tabs does not change the window 
state.

There are several possibilities:

The most elegant from a usability viewpoint would probably be one of the 
above: refactor the code.

Instead of calling show() on each Window you could call showMinimized().

You could experiment with setWindowState(windowState() & ~Qt::WindowActive).

You can find out about the state of your application by asking each window 
about its windowState() or simply ask QApplication::activeWindow()!=0.
