楼主可以参考下 下面的代码: 
private   void   CreateMySplitControls()//创建分割窗口   
        {   
            Panel   panel=new   Panel();//左边贴一张面板   
            panel.Dock=DockStyle.Left;   
            panel.TabIndex=4;   
    
            TreeView   tree=new   TreeView();//左上角一棵树   
            tree.Dock=DockStyle.Top;   
            tree.Height=ClientSize.Height*9/10;   
            tree.TabIndex=0;   
            tree.Nodes.Add("treeview");   
              
            Splitter   split3=new   Splitter();   
            split3.Dock=DockStyle.Top;   
            split3.BackColor=Color.Blue;   
            split3.TabIndex=1;   
            split3.TabStop=false;                       
    
    
            PictureBox   pic=new   PictureBox();//左下角全景图   
            pic.Dock=DockStyle.Fill;   
            pic.TabIndex=1;   
            pic.SizeMode   =   PictureBoxSizeMode.StretchImage;   
            Bitmap   overview=new   Bitmap("overview.jpg");   
            pic.Image=(Image)overview;   
              
    
            panel.Controls.AddRange(new   Control[]{pic,split3,tree});   
    
            Splitter   split1=new   Splitter();//面板右边画一个分割线   
            split1.Dock=DockStyle.Left;   
            split1.BackColor=Color.Red;   
            split1.TabIndex=1;   
            split1.TabStop=false;   
              
            ListView   list=new   ListView();//右上角一个表   
            list.Dock=DockStyle.Top;   
            list.Height=ClientSize.Height*2/3;   
            list.TabIndex=2;   
            list.Items.Add("listview");   
              
            Splitter   split2=new   Splitter();//表下面一个分割线   
            split2.Dock=DockStyle.Top;   
            split2.Height=3;   
            split2.BackColor=Color.Blue;   
            split2.TabIndex=1;   
            split2.TabStop=false;   
            
            RichTextBox   richtext=new   RichTextBox();//右下角一张纸   
            richtext.Dock=DockStyle.Fill;   
            richtext.TabIndex=3;   
            richtext.Text="richtextbox";   
    
            Controls.AddRange(new   Control[]{richtext,split2,list,split1,panel});   
        }

用JSplitPane,然后添加两个JPanel，JSplitPane有方向的。
