Add nullfield at starting & ending at each row of the gridfieldManager.And set style Field.Non_FOCASABLE to that nullfields.And set the default focus at buttonfield.

Note: nullfields must cover the remaining part of gridfieldManager.

you can use

 LabelField field = new LabelField("   ",Field.NON_FOCUSABLE)
        {
            protected void layout(int width, int height) 
            {
                // TODO Auto-generated method stub
                super.layout(width, height);
                setExtent((Display.getWidth()-(buttonField.getPreferredWidth()+buttonField.getPreferredWidth())/2, height);
            }
        };

as nullfield.
