If the point of the project was to build a viewer, I might start
with the GUI. Otherwise I always start with the model.

I'd never impose a pattern in advance even if somehow I rightly knew
where I must end up. Well, I would do it for fun or as a
demonstration, but not in normal operation.

Furthermore, I'm not troubled by beginning a bit under the skin, but
try always to implement a piece of the interface that the skin will
use.
