Is the following WP ‘output’ possible?

I have an existing site and I’m wondering if I can use WP to power certain sections in a specific way (rather than the traditional ‘blog’ format.

Here’s how I need it to work…

Once a week, I will post a new article, and I want the whole article to appear on the home page of my site (in a specific area). No other blog entries should be viewable on this page.

On 3 other pages of the site, I need just the Headline, and summary w/ link to appear (for the above article) in a specific area.

On a 4th page in the site, a LIST of the previous Headlines( with summary & link) will appear.

I hope I’ve been clear, and I hope this is possible.
