Then you have to use a different library for each plattform. I claim
that it is impossible to write a library which is able to refactor your
layouts keybindings and more. You also forgot to mention that each 
plattform has a different set of widgets, or similar widgets with different 
features. 
Either you hide features that arent available on every plattform, or
you reimplement missing ones, which might be impossible. You can look at 
wxWidgets for some examples.  

Maybe your library is implementable on a much higher level, as a sort of
code generation tool that manages the applications data model and provides 
plattform dependent views on the data.

I think that we should drop the wrapper idea for now. There are many
applications on Windows, OSX and linux, that do not follow the native 
look and feel, if something like that exists at all. All devs not happy 
with that situation should work on and with wxWidgets, until that
library is really portable and useable on all plattforms it claims to
support.
