you need to use an aggregator script, like CG-Feedread, or the built-in Magpie code, or something. That reads and outputs the html.
HOWEVER, in order to run the aggregator script/plugin code, you need some way to call it from a Page. There are three ways:
1. My CG-QuickPHP plugin gives a shorthand format for making single, simple, PHP calls within the body of a page/post. It's fast, but limited.
2. There are a few PHP-execution plugins that allow you to embed PHP code 'normally' into your page/post body. They're slower, but allow complex/unlimited PHP.
3. Make a custom page template that calls the aggregator, and assign it to the static page.
