Share Button Like SuperUser

Unless i missunderstood what you meant those facebook, twitter, google buttons looks
Simple. There are a lot of plugins that allow to pick the services you wish to
disply and also the way that they are shown

Check out (all sites – not just wordpress):

1. addinto.com
2. AddThis

WordPress Plugins:

1. Facebook, Twitter, Google Plus One social share buttons
2. Slick Social Share
3. Share Buttons Simple Use
4. Addthis for wordpress
5. Sharebar

.
If you want to build your own design you can easily use simple php scripts
to design “share buttons” with the look and feel suited for your website.

For Facebook:

<a name="fb_share"></a> 
<script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" 
        type="text/javascript">
</script>

(want to style it? visit here: facebook share button styling)

.

For Twitter (Put image instead of “Share on Twitte” Text):

<a href=”http://twitter.com/home?status=Currently reading <?php the_permalink(); ?>” title=”Click to share this post on Twitter”>Share on Twitter</a>

.

For Google Plus (Put image instead of “Google +1” Text):

<a id="plusone-icon" class="pngfix" style="margin-left: -17px;" title="PlusOne" href="https://plusone.google.com/_/ +1/confirm?hl=en&url=<?php if (is_home()) { echo site_url(); } else {  echo the_permalink(); } ?>">Google +1</a>
