You should first concentrate on the logic, then eventually design the GUI. There are several reasons for that:
* internal logic and UI are different points of view
* both aspects will be clearer; even if they progress in //
* if you mix them, then any change in the logic will require UI updates -- you will end up losing your time redesigning the GUI
