Dynamic web pages?

Lets say I wanna make a site with jokes.
Users can register and add new jokes. Every joke can be rated, and below,on click, you can see the comments. Depending on the rating, jokes need to be automatically rearranged and lets say I wanna list of top10 somewhere else.

There is a lot of similar sites, but I'm interested what do I need to know and which tools to use to make such site?
As far as I can see, I need php and SQL to do this, right? What are my options?

thanks

,,,,,,what do I need to know and which tools to use to make such site?......You will need or have access to someone with good skills in all of html, css, javascript, a server side scripting language (PHP, ASP, Java etc), SQL, database design and maintenance.

The tool I use to build websites is the Netbeans IDE (http://netbeans.org/) (Integrated Development Environment), XAMPP (http://www.apachefriends.org/en/xampp.html) as my local development web server and SQLyog (http://www.webyog.com/en/) as my sql gui.
