    public final static Dimension vpad20 = new Dimension(5,30);
    public final static Dimension vpad7 = new Dimension(1, 20);
    public final static Dimension vpad4 = new Dimension(1, 4);

Why don't you use a Layout manager?

GridBagLayout should a good choice, it is very flexible.

GridBagLayout is definetaly the choice, but its a bit harder to pickup than the rest of the layout managers. Once you're comfortable with it though, you wont use anything else.

You might also want to consider GridLayout, which simply places components in a grid. You'd just create a grid with 1 column and the number of rows you need, then add your components one at a time and they are placed in the grid.
