         frame.add(painel);
         JLabel login = new JLabel("Login: ");

                }


        }
   }

Answer 1

Only by error message you can already deduce: missed close some parentheses or keys.

In his method addActionListener you implement a Functional interface this way:

prime.addActionListener(new ActionListener(){
    public void actionPerformed(ActioEvent e){
         JFrame fr = new JFrame();
         fr.setVisible();
    }
}

Failed to close the parentheses of the method:

prime.addActionListener(new ActionListener(){
    public void actionPerformed(ActioEvent e){
         JFrame fr = new JFrame();
         fr.setVisible();
    }
});
