I checked after I posted the original and found that my webhost is offering wordpress as a 'one-click install' option. I'm sorely tempted to give it a try.

I'm wondering if I could have a really basic theme and maybe have it on the page as an iFrame so that all I would have to do is implement color code changes and keep the layout of the site the same.

My mind knows what I mean to say here but it also knows I'm not translating well.
