I want to create a web site using a service like Freewebs or Google Page Creator, but using a single list of links around the site gets tedious and long. Is there any free web site service that lets me edit a page hierarchy directly? Or is there a way to do this through Freewebs?

For example, the kind of thing I want to do is in this picture.
