GUI Design

Can anyone recommend any good books/blogs/websites on the subject of GUI design and usability, I'm getting to the stage now when I'm finding it hard to present all the necessary options to the user in a clear and concise way.

Tons of software allows the user to reconfigure the toolbars and menus.  That's great for somebody who's already familiar with the program and wants faster access to things he knows about.

There is no way to make a program easier for novices.
