Looking for a free tool to do UI design

Question

I'm gathering requirements and I'm looking for a free Visio replacement to do UI design. Does anyone know of a good tool I can use?

All I need is to be able to put together something that would look roughly like what the user would see on his screen (menus, buttons, text fields, and all the standard widgets).

I'm not looking for a UML tool.

I've seen some tools that look pretty good but will put their logo in the corner unless you pay. I'm looking for something that's completely free.

Thanks!

Try the Firefox-based Pencil tool.

I like Gliffy: http://www.gliffy.com

For a cheap paid version, people seem to like Balsamiq (http://www.balsamiq.com/).

The express versions of visual studio are free...
