Create a IM program (like MSN or Gtalk ) using C++
<p>My question is that create a IM software like MSN or Gtalk, to have the basic function using C++.</p>

<p>You can use any technology and libary to do that.</p>

<p>Can someone give me a suggestion?</p>

  <p>I add that this not my homework. This
  is my job question.</p>
  
  <p>Because I am a fresh man in my
  company.</p>
  
  <p>So, they give me some questions to let
  me dirty my hand.</p>
