java建立一个窗口，上面是一个按钮，下面是一个文本框，点击按钮之后，将连接SQL 数据库，将相关查询结果输出到文本框当中。文本框要做的大些，输出内容会比较多，急求，谢谢！！！
数据库查询语言：
SELECT Qcontent FROM (SELECT TOP 1 *, NewId() As RandomX FROM Q Where (K1='jx')AND(QTypeName='xz')AND(QDifficulty='1') Order By RandomX) A
UNION ALL
SELECT Qcontent FROM (SELECT TOP 3 *, NewId() As RandomX FROM Q Where (K1 NOT IN('jx'))AND(QTypeName='xz')AND(QDifficulty='1') Order By RandomX) B
UNION ALL
SELECT Qcontent FROM (SELECT TOP 6 *, NewId() As RandomX FROM Q Where (K1 NOT IN('jx'))AND(QTypeName='xz')AND(QDifficulty='2') Order By RandomX) C
UNION ALL
SELECT Qcontent FROM (SELECT TOP 1 *, NewId() As RandomX FROM Q Where (K1 NOT IN('jx'))AND(QTypeName='tk')AND(QDifficulty='1') Order By RandomX) D
UNION ALL
SELECT Qcontent FROM (SELECT TOP 4 *, NewId() As RandomX FROM Q Where (K1 NOT IN('jx'))AND(QTypeName='tk')AND(QDifficulty='2') Order By RandomX) E
UNION ALL
SELECT Qcontent FROM (SELECT TOP 1 *, NewId() As RandomX FROM Q Where (K1 NOT IN('jx'))AND(QTypeName='jd')AND(QDifficulty='2') Order By RandomX) F
UNION ALL
SELECT Qcontent FROM (SELECT TOP 4 *, NewId() As RandomX FROM Q Where (K1 NOT IN('jx'))AND(QTypeName='tk')AND(QDifficulty='3') Order By RandomX) G

急求急求，谢谢！
数据库是SQL sever 2000 数据库名称是 多层次试题库，登录名是sa 密码为空

Answer 1

首先你利用java swing进行页面的编辑，首先定义面板，将面板设置城表格布局(BorderLayout)然后将组建比如按钮和文本框添加到面板上，将按钮添加到North，将文本框添加到Center，然后将此面板添加到窗体中。对按钮添加事件监听器，里面指定你处理数据库的方法，例如:数据库的驱动连接，里面处理细节的方法，记住此方法返回一个字符串，然后将此方法返回的内容设置成你文本框的内容，这样就能实现你所要求的目的！

Answer 2

写个java链接数据库类，然后点击按钮，就执行这个类，在把结果返回

追问

我也知道，不会写啊
