Using Controller for .page files

System

I am curious about using the Controller to be able to capture content via one component and passing that to another component or to another .page file.

Example of what I am trying to do:

I have a component that is creates a news article and thus produces a .page file that is a html page with the article.

I have another component that creates a news summary page of all news articles. Basically the Article heading, title, and date is captured in this component thus creating a .page file that is a html page with the summary of articles.

What I want to do is automate this process so that when I create a news article page it automatically updates or appends the summary page with necessary information.

Is this possible using the Controller and if so...please give me a starting point.

Thanks
