some questions on how I should go about this project...

First off, sorry if this is in the wrong section, but honestly there doesn't seem to really be any other fitting category.

I want to create a blog as just a tiny feature in a mostly flash driven webpage (css/html with flash banner, flash login box integrating php and postgreSQL) and I really don't want to have to make it into a wordpress theme. I believe it would be too much of a hastle for me to make it a wordpress theme as its not the purpose of the site, just a side news feed type deal.

Also, I have about 50 pages worth of information (each page dealing with something new). Should I just stick with html/css or just on to some sort of CMS? I don't see the info being updated very often, but the pages will pretty much feature the same layout. Which way should I go about dealing with this in the CLEANEST way possible (Expansion and updates can happen in the future, just not right now).
