MDI's SDI's and Dialogs definitely exist in Qt. But, MFC and Qt differ
For MFC, some feedback seems to indicate that it is easier to use
specialized widget classes for the application type.
For Qt, a generic VTK/Qt widget is much easier to use.

That's an idea I hadn't considered yet either.

The view isn't different between SDI and MDI app. It is the document
related to the view that is different.
So perhaps we put a vtkMFCView class in which wraps the generic
vtkMFCWindow. Then integrating a vtk window into an SDI/MDI app is a
touch easier for the MFC people.
