Here's the problem:

       while( true ) {
          g.drawLine( startX, startY, endX, endY );
          newpoint();
          //this.repaint(startX,startY,endX,endY);
          try {
             Thread.sleep( 1000 );

You have to exit the EDT to allow it to update.  If you do a 
"while(true)", you have an infinite loop and never exit.  Hence, no 
output because the EDT can not run.

Look into using a Swing Timer instead of using a loop like this.
