Off-topic, irrelavant, and in deed, despite the half-baked disclaimer very racially charged. Aside from applications and human beings being two entirely different things, I fail to see how whatever terminology joshua uses to refer to caucasians influences who you date, african american or not. Furthermore, I sincerely doubt that you watching david chapel qualifies as a lesson in cultural differences or socialogy. Particularly considering it satire.

Anyways, as for the original dilemma, I believe that problems could be solved if, as was previously suggested, developers start writing their code as to decouple the UI with the rest of the code. In this way, a developer can continue to add functionality to his program while leaving the art of design to the..well..designers.

For Qt (and its bindings) a developer needs only become familiar with Designer. For GTK+, glade serves the same purpose. The only real problem that then remains is deploying to Maemo. While Qt at least allows you to select the "Maemo" style, the Maemo-specific widgets are not yet integrated into it. While it is possilbe to add custom widgets into Designer, that is a bit time consuming. As far as I know, the same holds true for GTK+ and Glade.
