I just installed WordPress myself and it was rather easy.
In order to help you: can you give an indication of the kind of problem you have?
I think that Softaculous will be a good choice if you are a newby. You can find it in the software section of your cPanel. In Softaculous expand the blogs part and select WordPress, then select the Install tab and fill in the fields with the Site Name, Admin Username and password. Then press install.
