No. Because GUI code is usually bigger and messier than the application
code. It is more fragile and requires much more maintenance. Furthermore it
is the only thing the customer sees and actually pays attention.

No. Maintenance costs are 10 times of developing costs. For GUI code it is
even more than that, because once deployed, the customer starts requiring
modifications. Whatever mythical productivity it does not matter in the end
