Make recursive calls to XtParent until it returns NULL.  This will give you
every widget parent of this widget.  Getting the names of each of these widgets
is tough, in R3 the only way to do it is to look at widget->core.name, in R4
there will be a public routine that will return the name of a widget.

Your idea is the right one, but you will need at least one widget in the tree,
since widget names need not be unique.  Think about multiple invocations of the
program on the same display, this is certainly allowed, and the widget names
are all the same.
