There is a trade-off between quick, simple apps and more complex
apps. Tools like Access make the quick, simple apps very easy, but
can make it almost impossible to create complex apps.
I'm spoiled. I come from the Visual FoxPro world, where you can do
just about anything you need to do. I don't want Dabo to be any less
capable.

It's more a question of: Developer A prefers Qt, while Developer B
prefers wxPython. The other main reason is if you need to develop a
Gtk app, and then later a Qt app, you only need to learn the Dabo
syntax, rather than two separate APIs.

Right now we are only supporting wxPython. Getting rid of its awful C
++ syntax is worth the effort to develop a clean, consistent UI-API.

Why stop there? Why not only support Windows? Or only Windows XP?
There is nothing in Dabo that would prevent someone with your
preferences from using only wxPython and PostgreSQL. There is nothing
that would prevent someone else from only using SQLite.
It's about choice. It's a much better approach than the Microsoft
way that many people have been stuck in.
