You could “fix” your widget to shortcode script, use the function the_widget() at the required point, just use an html form with the right field names or maybe even add a new widget area to where you want to use the shortcode.
But none of these ways is as fast or easy that I could write it for you. Unless how basic it seems, it needs to much time.

Have you tried to insert the settings in the $instance variable? You can find the setting names in /lib/widgets/form_widget from line 115. Then you need to make a string of it: “option_name=option_value&option_name2=option_value2”

Have you tried if the shortcode even calls the widget? Add a var_dump(123); to the widget beginning and see if it comes up.
