So I instantiate a Model object that handles all IO to the database.
Next I instantiate a Controller object, passing it a reference to the
Data/IO model object. Next I instantiate the display panel objects for
the GUI, passing them references to the Controller object.

The Controller object contains the logic for all the transformations I
want to perform on the data.
