Look into JSON. You could output the data in the desktop app as a JSON file and upload it to a webserver, then retrieve the file from the app with a HTTP request. If there is a lot of data or it changes rapidly you will need a more sophisticated server/client relationship where the app requests specific data from the desktop and the desktop sits around listening for requests.
