There are several ways to do this, and Magritte provides the building blocks
to choose the one reducing duplication most. In QCMagritte, we chain the
visitors building the form to do e.g. translations and access control.
In Magritte 'style' you'd want to prefer a declarative style with properties
over coupling the description strongly to the component.

Important for your choice in how to do this is also the question of
reuse. If you need it once, your first solution, or just a subclass is fine.
In a UI that adapts to screen size, you might want to avoid direct numbers
and use properties like large, wide, small to direct the layout
