Caveat: I'm not using Qt, I just tried this in IDLE (which is graphical).

C:\>copy con test.bat
echo Hello, world!
pause
^Z
        1 file(s) copied.


IDLE 2.6.5
>>> import os
>>> os.system("c:\\test.bat")
0

The 0 and subsequent prompt don't appear until the batch file
finishes. Meanwhile, the batch file is executing in a separate window.

When you try it inside Qt, do you get a background window that needs
to be brought to the front? Does execution pause while the batch file
runs?
