Repair or recreate php news page on my web page

I would like someone make (or repair) a simple webpage-part with the following parameters: Admin page: login with a user name (stored in a file) and a password. After the LOGIN process, the uploaded news can be seen, and these news can be deleted or modified in this way. Or new news pieces of information can be published. In the case of uploading new information, an address occurs on the top with a few words of introducing the topic (on html basis); and with a link on the bottom.... that is activated when the news is chosen. This is saved in our MYSQL system with timestamp. The other part of the project is a webpage where the news are listed with the title and the short introduction. Every news is in a box with title and date - created with proper css. But when someone clicks on the news, the selected page appears within the same iframe. This page would appear in a main page iframe. Our page where we would like to insert or alter this project: [login to view URL] The news box (big box with some Hungarian text) is bad now. I would like to change it for a modern new one in iframe.
