大家帮我看看我这个程序,很急迫!

这个程序就是一个能实现鼠标拖放的白版,我想问几个问题,一个是我想有一个button ,click后如何创建一个新的tag,我定义了一大堆TabbedPanel panel并且在lib目录下放了一大堆的TabbedPanel用来import这样做很是烦琐显的太笨拙,如何动态实现呢?  还有一个就是  backward和forward按纽click的时候能显示出前一个tag或者后一个tag上的图片,如何实现?  clear的时候我原来的图片怎么还是在tag上呢      谢谢啦!  很急迫!
//This project is to drag and drop images on tabbedpane, click
