Code (markup):

paste this in header or wherever you like show category bar

<div class="cat-menu">
        <ul><li class="page_item <?php if ( is_home() ) { ?>current_page_item<?php } ?>"><a href="<?php echo get_settings('home'); ?>/" title="Home">Home</a></li>
<?php wp_list_categories('depth=0&title_li=); ?>
			</ul>
</div>

Code (markup):

 

will it show subscategories on hover? (coz i see there is no mention of subcats in your code )

 

try it and its will show subcategories in the category bar , just try it its a wordpress inbuilt function
