You need to spawn a new thread when the button is clicked.

 button3.addSelectionListener(new SelectionListener() {
    public void widgetSelected(SelectionEvent event) {
        try {
            Thread t = new Thread(){
              int count = 0;
              setPressedIcon();
              while(count < 4){
                 try{
                  Thread.sleep(1000);
                  count++;
                 }
              }
              setUnpressedIcon();
            }
            t.start();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    setPressedIcon();///??
    public void widgetDefaultSelected(SelectionEvent event) {
    }
});

If you do it in the same thread as your UI, everything will be halted during the 3 seconds.
