Ok, you could find the steps to make your WPF apps have the Aero Glass Transparency over the internet, but I thought it would be nice to have a library which could make the job easier 
I have written a small library which you can use to make your WPF apps have the glassy look. Have a read here
I am also planning to include more features as I really see what options are available in the DWM. (Hope Kirupa can give some tips )
I would be happy to hear your comments/ideas/suggestions 
Thanks,
