Static page, dynamic

CMS & WordPress
1
  1. I’d like to design using WP as a CMS.
  2. I also understand that I can use any html page as the home page design as long as I add certain php code to the top of the page.
  3. I realize that I have to set the home page to be a static page and that many of the internal pages will also be static pages.
  4. I intend to have several dynamic areas of the site: events listing/calendar; internal news items, etc.
  5. I don’t want blog “posts” as such

What I want is a home page and other static pages that include a one or more sidebars with events listed from a calendar page. And perhaps news items. So this would be a dynamic element called from the dynamic pages of the site.

How do I have such a sidebar on a static page?
