New Design for Fat Calculator GUI

We will use GridLayout for the Frame of the fat calculator application. The idea is to arrange the components into a column like this:

The middle three cells will get the three Panels we have already worked with. The title could be put in the top cell, and the doIt button could be put in the bottom cell, but it the results are visually nicer if each of these components is placed in its own Panel, which in turn in put into the Frame.
