UNIX-based "Template" Software for Web Design?

jedinite asks: "I work for a large company looking to expand our web development offerings to cover lower-end sites. We are looking for a template-based program which we can offer our customers where they can "point and click" to develop their own website over the net. Basically, the user could provide a few graphics of a specific size, cut and paste some text as content, drag and drop a few links, and have a very basic website which they create & maintain themselves. I'm having serious trouble finding a package such as this which runs in our UNIX environment (we're mostly a Solaris/Apache house, but have some Linux/BSD boxen as well). Does anyone have any comments on or experience with any software package or module which performs this desired functionality? Anyone know of a software package for UNIX-hosted 'template web design'?" This is an interesting approach to the thought of homepage design. Thoughts?
