Here's a very low-tech way to do that. I think it would work.
Create a chunk called HomePageResources.
In it, put nothing but a comma-separated list of IDs that get shown on the Home page (no spaces).
Create another chunk (let's call it TeaserTpl) with tags to serve as the Tpl chunk for getResources and specify it in the &tpl property of the getResources tag on the Home page. Something like this:
<div class="resource_preview">
<p>[[+pagetitle]]</p>
<p>[[+introtext]]</p>
</div>
Put a getResources tag on the Home Page where you want them to appear, with these properties:
&tpl=`TeaserTpl`
&parents=`-1`
&resources=`[[$HomePageResources]]`
Now, all the user has to do to update the display is to note the IDs of resources in the Resource tree to be shown and type them into the chunk (and remove the ones that should no longer be shown). If they know the name of a Resource they want to add or remove (or part of it), they can use the search box at the top of the Resource tree to find out the ID.
