Is it possible from within an element display to use a button with associated QAction to launch another application on the users PC?

From what I can gather looking through Dataminer Development Guide I'm leaning towards it not being possible.

The background for this request is for devices that aren't compatible in the inbuilt Web Interface viewing option (ie: Flash or Java devices) for the user to click a button that launches the application required instead of trying to display the webinterface within Cube Client
