    Default Netbeans-generate number of radio buttons dynamically

    I'm creating a databse application with SQL server management as the back end and the GUI in Netbeans. Based on the number of rows or tuples retrieved from the databse, I want to create those many radio buttons. Currently I've just come to this:

    result = select.executeQuery("SELECT .......");
     
    while(result.next())
    {
         cpf=result.getString("CoursePrefix");
         cnum=result.getString("CourseNumber");
         String cname=result.getString("CourseName");
         jRadioButton1.setText(cpf+" "+cnum+" "+cname);
     
     }

    So, is there a way to to create radio buttons dynamically (something like jRadioButtoni.setText(cpf+" "+cnum+" "+cname)) where i is the number of tuples returned by the query in result.
    Also, in the GUI builder I have to drag and drop the swing controls. I cannot declare teh components via the source code.

    Any help and pointers in the direction will be greatly appreciated! Thanks!!

    well it can be done like this:
    Create a jscrollpane
    add panel to it
    Set the layout of panel to your desired layout
    connect to database and get the number of rows or tuples.
    call addRadioBtn(your jpanel's variable, no. of rows or tupples)
    void addRadioBtn(jPanel jp,int len)
    {
    	jRadiobutton jr[] = new jRadioButton[len];
    	for(int i =0; i<len; ++i)
    	{
    		jr[i] = new jRadiobutton();
    		jp.add(jr[i]);
    	}
    }
    Hope this help.
