Adding Widget Area to a Single Page

[NandoJourneyman]

I keep messing this up, so I figured I'd ask.

Here's what I'm trying to do: I want to have a page that shows the page content, as the page template normally would. Right after the content, there will be a widget area. While I imagine just about any widget could be used here, I intend to use the Genesis Responsive slider to show and scroll through several subpages' worth of content without having to navigate to them.

Ideally, this will be a full width page (no sidebars).

I can't seem to get a custom template to work for this.

Help? Pretty please?
