Google maps API documentation is here.

I used the following code in a little (desktop) app of mine, you just need to feed the appropiate set of coordinates.

<script type="text/javascript">
    var map;
    var latlng;
    var lat;
    var lng;
    var zoom;

    function Init() {
        lat = 40.632915;
        lng = -8.68929;
        zoom = 18
        latlng = new google.maps.LatLng(lat, lng);

        var options = {
            zoom: 18,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.SATELLITE
        };

        map = new google.maps.Map(document.getElementById("map_canvas"), options);
   }
</script>
