If you want to build it yourself, a *very simple* idea would be.
A news table in MySQL with ID, title, article & date fields.
You'll then need a couple of admin PHP pages to add/edit & delete articles, how you secure these is a different matter.
Then you can select the articles you need on you home page, and on your new pages.
I did have a website setup like this, but recently did a whole refresh and switched to Wordpress as my needs out grew my own system.
