I believe only the same application can push updates to a widget. I know I wouldn't want other apps to be able to send updates to my widget directly.
The proper approach would be to handle it with your AppWidgetProvider subclass (remember this is simply a BroadcastReceiver with some help for widget-specific events). Register it for a "com.whatever.CALENDAR_UPDATE" event, and allow other apps/services/ whoever post requests to add/change/remove calendar events. Your widget provider class can then do any security or sanity checks on the request before posting the update to the on-screen widget itself.
