parent child relationship between panels using java swings -

-

I need to create a desktop application for the client using Java Swing and jdk 1.6 . Requirements to display a series of elements (text-field, buttons, labels in each element) in the parental form, such as: 

  Parents 1 Child 1 Child 2 Children 3 Children 3 1 child 3/2 indentation will be used to display the original childhood relationship   
 It looks like a  JTree , where the button in each node , Labels etc. are included. How can swing components be used?   
 
 
 using simple vertical  boxlayout  or  gridlayout  blank border  with each left offset to each element where the offset left element (from 0 to root +0 for each level) ) Is calculated.
