well, .. i always recommend learning php/mysql since it is such a powerful combination, and there is a wealth of information all over to help you.
you are describing a cms, or content management system. it is a tall task for your first project, but definately a good goal.
php syntax is a lot like javascript. i would recommend setting up a mysql databse and learning how to query and get results from the database.
you can install it all on pretty much any platform, and develop locally, .. or get some cheap webspace somewhere so the rest of the world can see it.
let us know if you need an idea where to start =)
have fun! .. and put down that playstation .. coding is more fun
( and pays better too )
