nathaliev, whether or not you want to use wordpress as the site is up to you but it can certainly be done. http://www.techcrunch.com/ is an example of one that is very popular.

Wordpress also offers adsense plugins and tutorials for implementing them throughout the site.

There will be a learning curve but I think you will find it easier than both Joomla and Drupal and should provide a nice stepping stone to understanding those CMS programs.
