Don't create multiple parent-less top level frames in layout sample.

This resulted in unexpected behaviour if the main frame was closed while the
other ones were still shown as they remained shown and had to be hunted and
closed one by one to make the application exit.

Fix this simply by creating all the other frames as children of the main one.
This also results in better UI when minimizing and restoring the main frame.

Also get rid of unused position parameters in child frame constructors and get
rid of the title parameter which is not really needed as it's always the same
too.

See #11923.
