Is it possible to start a workflow from a portal widget?

Hi guys, there's a way to start a workflow from a portal widget? 
In particular, I'm using a custom button and a workflow should start when the button is pressed.
Thanks, Giovanni

Yes it should be possible.

1. Create script include and trigger workflow using startFlow method.

2. Call script include using GlideAjax from client controller or directly call the script include from server code.
