That is the problem.

I need to run on compute-farms machines which will not support GUI activity.

That is the rub. Layout is a general need.
It is too bad that Qt has tied it so closely to GUI when there
is very little need for GUI. All the top level of a layout needs
is the size. It does not need to be the size of a QWidget.
