...and there's another HIG at least as relevant to Qt applications, if not more so:
http://techbase.kde.org/Projects/Usability/HIG/GroupBox
The list
* Always try to use a group box to arrange related controls.
* Use a frame to arrange related controls that cannot be labeled.
* Do not group single controls.
* Consider to communicate relationship by layout only.
from there seems to limit the places where group boxes should be used.
