If your pages can all be just static files, you can configure the site mail url in GSA and it will index based on sitemap. Or else, you can write a agent to post content via gsa api and index on modification of pages and assets. To show the response , you need to get the data as xml and parse and display on the page. Adobe SearchandPromote does something very similar and much more and has OOB integration. Please have a look.

I couldnt find any article/document on integrating with GSA. As we know GSA is a crawling search engine, you can use GSA APIs to build your index and search from the index. We had done this in one of our implementation. I will try to come up with a document in couple of days and see if it helps you.
