In your functions.php register a dynamic sidebar area:
register_sidebar( array(
'name' => 'Main Sidebar',
'id' => 'main-sidebar-1',
'description' => 'Here you can place widgets for the main page',
'before_widget' => '<aside id="%1$s" class="widget %2$s">',
'after_widget' => "</aside>",
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>',
) );
This sidebar appears in the widgets admin page, now. You may add your widgets.
In your main page template put a call to your new sidebar area dynamic_sidebar( 'main-sidebar-1' )
Probably you need some additional DIV to get proper results.
