Joomla requires PHP (the web scripting language) and at least a database like MySQL in order to be installed. Hostmonster supports both php and mysql, so running Joomla would not be problem at all. If you want to further customize settings you can do this via .htaccess or via php.ini. You can install Joomla with Fantastico one-click installer or manually.
