Taxonomy-Based Navigation Block w/ Node Titles

Hello all,

I need a taxonomy-based menu/navigation block that works like this:

Vocabulary title <- links to vocab view
+ Term <- expands to show node titles
Node title <- links to node
Node title
+ Term
Node title
- Term
- Term

So that the block doesn't get clogged up with a ton of unneeded node titles, the node titles should appear under the term only if the term is clicked.

Does anyone have any ideas on how to best achieve this? I am not yet familiar with coding for Drupal (or coding at all, for that matter), so I prefer solutions that don't require me to do so, though I'm willing to try anything out.

Thanks!
