I would optimize it for smart linking and a console widgetset.

Why should qt render a native button, if they can draw a qt button with a
'native' looking theme? Are you sure, that qt uses native widgets?

Yes, by reinventing the wheel.

A Mac user will be confused if she sees this menu.
A disabled person wants to use his OS features and not setup this for each
program.

Only the API is limited to the common features. The program is not limited.
As said above: You get extra features of the widgetset.
And if a programmer needs uncommon things, he can write a specific control. See
for example the printers4lazarus or the lazopenglcontext package. They started
on one platform and nowadays they run on all majors.
