How to make my front page display only the most recent sticky post, plus usual widgets?

Question

WP 3.3.1, Suffusion 4.0.2

I am trying to figure out how to make my front page display only the most recent post marked sticky. I can't find how to do this in the documentation.

What I'm trying to do is use a combination of future post publication dates and expirations (via the Atropos plugin) to control what shows up on my front page.

Any suggestions? Is there a plugin that has a shortcode that lets me insert the most recent stick post?
