UWP is a complete separate runtime environment on Windows. 
It is nothing like the Win32 API. 
You may not use the Win32 API directly in a UWP application.

That means the headers need to be ported, an RTL needs to be written on top of that.
It's still a question to me whether it sports a flat or OOP model (I think the latter). 
There are some other restrictions as well.

See
https://en.wikipedia.org/wiki/Universal_Windows_Platform
and
https://en.wikipedia.org/wiki/Windows_Runtime

All this means you must basically restart from scratch.
