The current trend for GUIs is for them to be declarative, data-driven,
and as automatic as possible.
Basically, what would be nice, is specifying what data you have, what
data you want, and not have to deal with any other detail.
The system should then automatically select the most suitable widget,
with the suitable disposition and sizes, and resize everything
automatically on window resize etc.
What you're suggesting is a fairly low-level widget interface, that is
far from covering all things it would need to cover.
For this, I'd suggest using an existing library like Qt, and write your
declarative data-driven system on top of it.
