so you're suggesting:
-write core algorithm(model)
-link algorithm(s) with each other and a central menu, if
applicable(controller)
-write views for gui or cli(view)
this is actually the path that i follow when writing django apps, and
is the sequence that is being used in "Practical Django Projects",
where first the different classes/data structures are written, then
linked together through the url file, and finally html is written for
each "view".
