如何使JPanel项目在同一个BorderLayout中的另一个项目下进行？

我想让我的JTextField（desc）下JSpinner，（dayspinner），但我不知道如何。如果我把文本字段放在SOUTH中，它就会一直走到窗口的底部。我也想用我的开始菜单来实现这个问题的任何解决方案，其中3个按钮紧挨着，我宁愿将它们放在另一个上面。如何使JPanel项目在同一个BorderLayout中的另一个项目下进行？

不要使用BorderLayout，它的设计没有做你想做的，考虑尝试使用类似GridBagLayout代替，这是更为灵活的

我有一直在尝试使用GridBagLayout，我绝对看到它可以做我想做的事，但我只是不知道如何。如果你想更多的帮助，这里是一个链接到我发布的新问题[链接]（http://stackoverflow.com/questions/29811091/how-does-gridbaglayout-functions-such-as-gridwidth-height -and-的gridx-Y-工作到SC） –
