            }
        }
    }
}

no, that's not what you want :-) In Swing/AWT, sizing and locating is the task of the LayoutManager, always. Your tasks are a) define the visuals of your ui (relative positioning/alignment/resizing behehaviour) b) find a LayoutManager that suits your requirements — kleopatra, Apr 14 '13 at 10:51
read the tutorial chapter on LayoutManager (click the tab "info" and follow the swing tutorial link) to understand which manager does what (hint: GridLayout makes all components the same size and uses all the space available) — kleopatra, Apr 14 '13 at 10:58
