How to display HTML page using BrightScript

I would like to display a single HTML web page on a Roku channel. I have no need to follow hyperlinks, but the page does have periodic updates.

Is it possible to write a BrightScript application that uses Gecko to render the page, or would I have to draw the page myself?

I see plenty of information as well as examples in the Roku SDK that describe how to provide user navigation and play video on a Roku box using BrightScript, but I can't find any information about displaying a single HTML page on a Roku channel.
