or if you don't want any reference of the main_window class inside the
class2 (loosing coupling) you can use a signal to implement a sort of
observer pattern [1].

class Clas2 {
    public signal void update_interface (args...);

    private void method2 (args...) {
        update_interface (args....);
    }
}

and on the main_window class you subscribe to the signal and then call method2:

class main_window:... {
    public Clas2 cl;

    public main_window () {
        cl = new Clas2 ();
        cl.update_interface.connect ((args...) => { method1 (); })
    }

    public void method1 () {
       ....
    }
}
