Custom fields with wysiwyg

I am making a protfolio page and want to include some project-specific info and a gallery. Here is a link of a screen shot of the design: https://img265.imageshack.us/my.php?image=screenshotuz5.jpg.

I understand that I can use the ‘get custom values’ plugin, but is it possible to get something like that but with a wysiwyg bar?

How would I dit this?
