The first thing you need to learn is Android and Windows 8 programming. There are plenty of good articles here on CodeProject to get you started.

Using Xamarin and SignalR can be an option worth exploring .

Can use Google Cloud Messaging API( GCM ) for the notification needs.

Thanks Jo for the response i have been studying the signalr and GCM for a couple of days. It seems to solve out but they both doesn't provide any client side acknowledgment. GCM notify only the message till the server but not is the message is read by the client. Is there any way to get this notification? If i use a custom notification like device on reciving message response back the server with the recived message id ,but how does it reflect to the sender in real time. Please help me out in this.
Any idea how this is working in watsapp? Watsapp notify user that the message is sent and when user open the chat it mark that sent message as seen in real time at sender device message list.
