Modifying a GUI without recreating it

[Demian]

Is there a way to modify existing objects and and new objects to a GUI without deleting and replacing it?

parentObject.add( newObject );
parentObject.remove( oldObject );

In some cases, this problem arises when modifying GUIs after they are created, though.

and if the object you wish to add to has no name you need to go to the closest object with a name and do objectName.getObject(0).add(newObject); or objectName.getObject(3).getObject(1).add(newObject); and so forth and so on.
