Master-Detail "Look and feel"

Hi, I have been searching for a tutorial on creating a menu like Gmail master-detail. I can do the functionality. I am just curious as to what controls are used to build that. My guess is.
Content.content

I want to create that beautiful looking menu with the icons. Is there some tutorial that discusses actually building that. Every tutorial assumes the person wants the Master-Detail functionality but I want the LOOK and Feel.

Any help is appreciated.

Thanks
