written when tired and drunk?

an angry diatribe written when drunk?

IME, a simple toolkit which is trivially easy to learn quickly ends up becoming restrictive and you spend more time working around its limitations than coding the app.

OTOH, a really really complex toolkit which allows you to do anything can have a very steep learning curve and take ages to write anything trivial.

Lots and lots of people have tried to come up with a good compromise, and some have been successful (QT from Trolltech), others failed or stayed in their niche markets.
