In a previous Win32::GUI app I provided both a CLI and a GUI interface.

I used one class for the actual application/business logic, one base class 
for the abstract UI and one subclass each for the CLI and the GUI interface 
(that is basically a variation of the Model-View-Controller pattern with 
the View and Controller merged).

The interfaces between the app/GUI-classes had to evolve a lot during 
implementation since I didn't anticipate many of the interactions between 
the app and the UI. An interesting observation is that the actual business 
logic was kind of small compared to the UI code.

I designed the UI subclass for Win32::GUI as a singleton to avoid all the 
global vars. Ideally I would like to see the option of subclassing e.g. 
Win32::GUI::Window and have the event methods called as methods on that 
object instead; the singleton is really just a workaround for that.
