Diego, You'll first need to be familiar with GWT<https://developers.google.com/web-toolkit/doc/latest/tutorial/>, then the Google Maps JS API<https://developers.google.com/maps/documentation/javascript/reference>, and then choose a GWT Google Maps API wrapper.
You could also start with the examples for the Google-Maps-V3 API here: http://c.gwt-examples.com/api/google-maps-v3 Sincerely, Joseph -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
