No offense, but if you have to brains to install centos-webpanel you can install Wordpress as well...
1. Download Wordpress
2. Create the User on CWP
3. Connect through an FTP Client for example Filezilla
4. Upload files
5. Follow the simple instructions on the screen.
Notice - You have to login to your MySQL Database and create a new database for Wordpress, this can be done through PHPMyAdmin or another client. Same username and password as to the user you created earlier.
Kind regards
