Any pluging that will let me to use any site structure on WordPress?

Hi. My problem is: I can develop websites but not for WordPress and I don’t have time to learn it. I build my sites on Dreamwaver, and when this software doesn’t provide me an easy way to implement some function, I just search on google and learn how to do it. I found a free plugin called Muse to WordPress redacted that lets you easily make your Adobe Muse sites work on WP and I tested it and it can work with any html site created with any software. This is awesome because I can build my sites the way I want and then use some plugins like Advanced Custom Fields to make content editable. But the only problem is that it doesn’t accept index.php but only index.html files, and sometimes I need to work with php. So, could you please tell me if there’s another plugin that will let me to use both html and php sites on WP without worrying about all the stuffs like header, footer, side bard etc.
