This is not a big change from the code I wrote. Instead of printing
the values, return a dict mapping names to values:
  return dict((name, widget.get()) for name, widget in self.widgets.items())

Then in the caller, use setattr() to set the attributes on self:
  for name, value in returned_values.items():
    setattr(self, name, value)
