Porting an ncurses app to Win32?

I've written a simple ncurses application in C for AIX 5.3 that mainly 
uses the menu library. Now I've been tasked with investigating the 
possibilities of porting it to Windows XP.

How would I go about doing this? The actual porting of the code 
shouldn't be a problem, but I'm not sure how to set up a C development 
platform on Windows (I've always worked in *NIX). What compiler should I 
use? Is there a native Windows gcc that I could use? Does ncurses even 
work on Windows? I've managed to compile my application on Windows using 
Cygwin, but for the production version it would be better not having to 
rely on Cygwin.

I've searched this mailing list, but I didn't find anything useful.

Thanks in advance.
