Help for beginner on CMS?

I currently have a static html site, I want to add additional pages that would use Joomla Drupal, Wordpress, javascript?????? to establish the task below:

I simply want users to fill out a small form with the date and time, descripion, location ect.. of an upcoming event. Once the form is completed I would like the description of that event to automatically show up on a seperate page. The seperate pages would be categorized by different types of events, which the user would have choosen from a dropdown menu when filling out the form. On the main page I would probably be listing all of the events entered, and allowing them to sort by category.
What is the best way to accomplish this?
Is there a fairly easy script already created for this/
For a fair price, I would be willing to hire out?
Thanks

 

If I understood you correctly you'd like to keep your current site & add this widget to it, right? So it better to hire someone & ask them develop a custom script.
Otherwise you'll need to start from the beginning, create a site & then add the feature needed

 

Correct, I need a script to incorporate into an already existing html site. I'm sure there is a script that already exists, whether it's php, joomla????
