title: How to add buttons and other components dynamically with free layout in swing?
body: <p>Hi i am new to java swing. 
  i have to add buttons dynamically , when i try to add those buttons dynamically it does not add to panel when it is in free layout. it accepts any one layout like null layout or gridbaglayout. </p>
  
  <p>Is there any other way to add components dynamically with free layout?</p>
