Do you really want to create or just to install a CMS?

You should really just take an existing CMS and configurate and extend it the way you need.

You should extend your " a bit" in PHP, SQL, Html and Css and after this youre maybe able to create your own CMS.

A CMS is only a solution to manage your contents on your site. Thats the reason why its called Content Management System. ;)

You should furthermore know that you´re not able to build your own cms within 24 hrs. It takes a lot of time and in some situations its much more useful to use cms from other users ;)

Btw if you have your own cms you have to secure it too and for this you should know what you do.

If you are not able to find the ressources you need for this using google, I highly doubt you have the knowledge and skills to code your own cms.
