How to apply style for WPF window look like office 2013

HI

I want to create a WPF application with the window style look and feel same as MSOffice2013. I don't want to use windowsStyle="None" and Allowtransparency="True" as WindowsFormsHost will not show if I make AllowTransparency = True.

1.Please suggest me whether i can create WPF application in window 8 VS2012 to achieve the same . if so, do i need to use any themes or styles which will give the same(MSOffice2013) look and feel in windows 7 ???

2.OR I can achieve this on Windows7 VS2010 itself ??

Please share any samples or links for reference

Note: I need to use WindowsFormsHost control in my WPF Window.

Thanks
