Is there a book or site that walks through the creation of a real business application?

Hi Experts,

I'm just wondering if there is a book, tutorial, or a site that walks through an entire application from rough subs that connect to a database to refineing the rough corners on the UI.  Any type of application would do, so long as database access is invloved.  Maybe it would include tips on making the UI more appealing and less "window clunky" like the default look that you get from Visual Studio.  Any help would be appreciated.
