I found a wordpress theme that I really enjoy, however, I already have all the code written for my forms/DB and whatnot in PHP.
I've never worked with wordpress before, but I did just download a couple free themes to see what's going on. Am I missing something, or can I just cut out the code I don't need, and essentially use the frame as a layout, and insert my code where I want it? I don't want to invest a few days of work to realize I made a big mistake.
WordPress theme have it own structure to work for WordPress. If you need use the design, you may take out the style.css and modified the DOM for your own use.
