GTK themes on windows

[Deekshit M <dmantamp yahoo com>]

Hi all,
   I wanted to know how do I add a theme to the
windows application, that I am am developing on
windows. I could see that, when I change the theme
using theme-selector applictaion, the theme for the
GTK-demos get changed. But not for my application. 
So,
1) How to make these thinsg work for my application ?
2) How to apply the themes available at art.gnome.org
to my application on windows
3) How do I write my own themes? Is therte any
document for the same ?

Thanks
