I want to build admin side application using CMS.

I check following templates.

I want to develop admin CMS applications using WordPress, Drupal or Joomla.

I will not develop front-end of the application but backed admin using CMS.

I am not getting how to make admin template working with CMS.

Any Idea?

Thanks & Best Regards.
