If your WCF is hosted in IIS then add a service reference to your windows service. Now it will create you a proxy.
Now you have to create a callback class and implement your CallbackContract Interface from WCF service. NOw when you create an instance of your service proxy, you have to give this callback implementation to the proxy constructor. Now when you call the WCF service, You will get the callback in your callback implementation.

Solution 2

you can do this.
Now tell me if you have a wcf service already in place?
If yes then have a look into the service implementation to find out if there is any Callback contract defined.
Callback contract will be an Interface with [OperationContract] attribute on the callback methods.
This callback will be refered by the service contract.

Now find out how the wcf service is hosted. If it is hosted in IIS, Self hosted, within application...

Now answer to my questions and i can help you.
