I need to modify a PHP script and integrate it with wordpress

i bought a PHP book search engine script which works with google books API.

I need to modify it so i can make it work with just my book database (i own a library with about 1000 books).

I have basic PHP and MySQL knowledges, but i am in the learning process…

What would you recommend? could you help me if i send you the script?

Can i integrate it with wordpres so i could, for example, upload my new books easily via admin panel?

Thank you so much, as always, WPMU team
