Why don't you try ActionListener instead? It works for buttons:

Code:

... // change your class line
public class Connect extends JFrame implements ActionListener, MouseListener {
... // change those listeners
buttonC.addActionListener(this);
button.addActionListener(this);
... // Add this somewhere:
public void actionPerformed(ActionEvent e) {

    if(e.getSource()==buttonC){

    try{        
    host = InetAddress.getLocalHost();


    ChatClient client = new ChatClient(host,port);
    client.start();
}
    catch(Exception ex){
    ex.printStackTrace();}

}
    else

    if(e.getSource()==button){
    this.setVisible(false);
}
...

As for another you might have been having, make sure to compile ChatClient before Connect.

Hope this helps ^_^
