Blend and C#

I dont know if this is possible, but is there a way to create GUIs for programs that i write in Visual C# Express 2008?

Say i write a program that does bank transactions. I know you can create GUIs using C# System.Forms and stuff, but i just want to know if you can create GUI in Blend and apply it to C# programs. It would be much quicker and look cooler if this is possible.
