No need to use a promoted widget.

Add a QTreeWidget and give it the name of your field (attribute)

Create a python plugin that registers a custom widget like the one in
the referenced blog post.

Within the widget code:
 * setValue: needs to convert your attribute value to the gui
 * value: translates from gui to attribute value

If you want to be able to use it with autogenerated / d'n'd designer:
 * createWidget: return a QTreeView
 * initWidget: fill your tree view with values (or do it in the designer
and don't do anything in here)

Is this enough information or is there anything in particular where you
need more?
