It is native to wxPython TreeCtrls:
    tree.SetPyData(node, data)

Creating your own tree, if wxPython did not offer such functionality
already, would be fairly easy.  The trick is that while you may not
expect tree nodes to share names, other trees that could use such
functionality may expect to share names, so using node names as keys in
a dictionary probably isn't the best idea.  You could use tree node ids,
as I believe those are unique within the tree.
