you can create new widget area.
function header_widget_areas() {
register_sidebar( array(
'name' => __( 'header', 'header' ),
'id' => 'header',
'description' => __( 'Insert something for about us text.', 'header' ),
'before_widget' => '<div class="widget span3">',
'after_widget' => '</div>',
'before_title' => '<h4>',
'after_title' => '</h4>',
) );
}
add_action('widgets_init', 'header_widget_areas');
Then place your widget in that area from appearance.
Then in your template where you want to display widget past this code.
<?php if (function_exists('header_widget_areas')): ?>
<?php dynamic_sidebar('header'); ?>
<?php endif; ?>
