I would recommend a 'fun' one like macromedia flash. he could post stuff on his website and get immediate "wow" responses from his friends. After that, I think java or Delphi are the first development languages he may want to learn. They are good for accomplishing many tasks and Delphi is a great 'gaming' development tool and it helps to know Java and Pascal too for college level courses later.
