diagram.getChildren().add() is the right way. But you can't add an element 
(e.g. UseCase) to a collectuion of diagram children; you can only add nodes 
(references) there.

the code below creates a diagram reference 
(com.borland.tg.emfapi.diagram.Node) for element and adds it to UseCase 
diagram:

UsecasesFactory ucFactory = 
UsecasesFactory.REGISTRY.getFactory(_paquetage.getIProject(), 
_paquetage.getSession());
    DiagramFactory diagramFactory = 
DiagramFactory.REGISTRY.getFactory(_paquetage.getIProject(), 
_paquetage.getSession());
//create a new UseCase diagram
    UseCaseDiagram myUseCaseDiagram = ucFactory.createUseCaseDiagram();
    myUseCaseDiagram.setName("MyUsecases");

//create a new UseCase
    UseCase myUseCase = ucFactory.createUseCase();
    myUseCase.setName("MyUC");
    _paquetage.getOwnedMembers().add(myUseCase);
//create a new reference
    Node node = diagramFactory.createNode();
//set usecase created above as reference's element (node becomes a shortcut 
to myUseCase)
    node.setElement(myUseCase);
//now add this shortcut to the diagram
    myUseCaseDiagram.getChildren().add(node);
//this is just FYI - bonus: how to set positions for the newly added 
shortcut
    Bounds bounds = diagramFactory.createBounds();
    LocationStyle style = diagramFactory.createLocationStyle();
    style.setLocationSetByUser(true);
    BoundsStyle bStyle = diagramFactory.createBoundsStyle();
    bStyle.setBoundsSetByUser(true);
    node.getStyles().add(style);
    node.getStyles().add(bStyle);
    bounds.setX(100);
    bounds.setY(200);
    bounds.setHeight(80);
    bounds.setWidth(50);
    node.setLayoutConstraint(bounds);

Cool! And thanks for the bonus!
