You need to overwrite the following figure of your diagram edit part:

	protected IFigure createFigure() {
		FreeformLayer l = new FreeformLayer();
		l.setBorder(new MarginBorder(50));
		ToolbarLayout lm = new ToolbarLayout();
		lm.setSpacing(10);
		l.setLayoutManager(lm);
		return l;
	}

(and don't forget to set the @generatednot tag, otherwise you loose your 
configuration after regenerating the diagram editor)

By setting the spacing (lm.setSpacing(10)) you can affect those.

See GMF Recipes "HowTo add children in a GMF compartment at a specific 
position" at:
http://wiki.eclipse.org/GMF/Recipes


Another hint: If you want to do the same for compartments set the 
listLayout attribute (GMFGen)  and again overwrite the createFigure method.
