Add Plugin to homepage

I wrote a widget that uses :
add_meta_box('repeatable-fields', 'Widget', 'repeatable_meta_box_display', 'post', 'normal', 'default');

to add a meta box to the admin panel for post pages and then uses :
add_action('get_sidebar','my_widget');

to add the widget to the side bar on those pages.

If I add :
add_meta_box('repeatable-fields', 'Widget', 'repeatable_meta_box_display', 'page', 'normal', 'default');
then it also appears for pages that are of the page type, or any other post type can be added to add to the post type pages.

So my question is how can I add this widget to the home splash page. I need to know where to go to edit that page in the admin-panel and any suggestions on how to actually include my plugin wound be helpful. Thanks in advance.
