You need a thread, which is checking the condition every so often

class MiHilo extends Thread {
    public void run() {
        int bandera = true;
        do{
            Calendar c = Calendar.getInstance();
            int seconds = c.get(Calendar.SECOND);
            int minutes = c.get(Calendar.MINUTE);
            int hour = c.get(Calendar.HOUR);
            String time = hour+":"+minutes+":"+seconds;
            txtHour.setText("Tiempo es de : " + time);
            if ((hour==3)&&(minutes==23))
            {
               botonJAVA.setEnabled(true);
               bandera = false;
            }
            Thread.sleep(1000) //para que se revise cada segundo, va por milisegundos
        }    
        while (bandera == true);
    }
}

Then in the main() or where you occupy it, you call the thread

Thread hiloReloj = new Thread( new MiHilo(),"hiloReloj " );
hiloReloj.run();
