Fantastico de Luxe is commercial cPanel addon that HostGator offers for fast one-click installation of popular web applications. Included are: WordPress (blog software), Drupal – Content Management script (CMS), Joomla – CMS, shoppin carts – zencart, oscommerce, forums – phpbb, mybb, galleries, polls and other cool scripts. What Fantastico does is setup/create databases and users, create tables and setup initial settings and permissions for the selected software. Though Fantastico is popular one-click setup tool it is not recommended by most developers of the popular scripts mentioned. This is because the latest version of the software is not available always (or at least not immediately) after it is published. So you may end up installing old version with security holes and bugs. So the better way is to manually install the software. I use fantastico only when I am installing wordpress, and update it right after login with wordpress automatic update tool. Here is a screenshot of Fantastico:
