put it into a basically blank page and call it from a web browser.

yes.

That's what the [tree] tag is for. I have a tree which can go as deep as you
like. Each record has field which defines its position in the tree. I use
this for a (sort of) file manager. The tree can go as deep as you like and
each level can have more folders (branches) or files (leaves). I have one
'tree' page which is called with a parameter which indicates where in the
tree to start; this could be the root, or anywhere else further down.
