Php news

Hey all, I have my html layout done and only need the content:

How would I start making a little php news script, were the headlines have to be in a cell on the left, but the info/text have to be in a cell on the right? And when you click the headlines on the left, the text in the right cell is changed. I will use .htaccess to access the admin section, where you can add, delete and edit the news. The news need to be in the order where the last added news is on top

It will have to look something like this:

Headline 1 | Text for headline 1 bla bla bla bla bla bla bla bla bla bla bla bla
Headline 2 | bla bla bla bla bla blav bla bla bla bla bla bla bla bla bla bla bla
Headline 3 |
Headline 4 |

But when you click the headline 2 link, the text is changed to the headline 2 text.

Could anyone help?

BTW; Is it easier with mySQL or .txt file, I have a db. And I would like to use .htaccess as login/pasword for the admin news area, where you add, delete, and edit the news.

I have also tried searching for free php news scripts, but no luck as I cant enough to tweak them to what I want.

Thanks for any help you may give,
