To realize this app I think you should not confuse Android Notification with GCM push Notification. What you see in the android status bar are Android notification and you can show it using the Notification Builder class:

 Notification noti = new Notification.Builder(mContext)
         .setContentTitle("New mail from " + sender.toString())
         .setContentText(subject)
         .setSmallIcon(R.drawable.new_mail)
         .setLargeIcon(aBitmap)
         .build();

So I think you can send a text message using Android api as example from the web:

SmsManager smsManager = SmsManager.getDefault();
            smsManager.sendTextMessage(phoneNo, null, sms, null, null);
            Toast.makeText(getApplicationContext(), "SMS Sent!",
                        Toast.LENGTH_LONG).show();

And you do not need to use GCM push notification

to open the an activity from notification you can use:

NotificationManager notifManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notif = new Notification(icon, mess, when);

Intent notifIntent = new Intent(context, Activity.class);

notifIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
        | Intent.FLAG_ACTIVITY_SINGLE_TOP);

PendingIntent intent = PendingIntent.getActivity(context, 0, notifIntent, 0);

notif.setLatestEventInfo(context, title, mess, intent);
notif.flags |= Notification.FLAG_AUTO_CANCEL;
notifManager.notify(0, notif);
