/** \brief A function to automatically generate a GUI using the parameters
\return Generated widget
This function just goes through each parameter, and calls it's 'get_widget'
function to get each widget. Then, each of those is placed into
a Gtk::VBox, which is then returned to the calling function.
If there are no visible parameters, this function just returns NULL.
If all parameters are gui_visible = false NULL is returned as well.
