Add custom fields after post/page title

Question

I am using the Headway theme, and I need to add custom field code to page & posttitles. This is what I need to be able to do.

The red button will be added through a custom field. It needs to be shown inline with the title. I have worked out I can do this using the headway_after_entry_title hook, but I can't seem to get the code right to retrieve the custom fields. I got this far :

//Add custom field image after entry title 
function title_btn() {
    echo '<div class="title-btn">[custom field code to go here]</div>';
} 
add_action('headway_after_entry_title', 'title_btn');

and the outcome should be:

<a href="xxx"><img src="xxx"></a> 

where the xxx is the custom field url code

Hope anybody can help me out with this.

There's the get_post_meta() function to retrieve those data.

So basically, you'd write a function in your functions.php file (or in a custom plugin - take "Hello Dolly" as example) and hook it.

<?php
/* Plugin Name: (#66495) »kaiser« Headway Title Button */
function wpse66495_headway_title_button()
{
    return printf(
         '<div class="title-btn"><a href="%s" alt="%s"><img src="%s /></a></div>'
        ,get_post_meta( get_the_ID(), 'meta_key_link_url', true )
        ,get_the_title()
        ,get_post_meta( get_the_ID(), 'meta_key_thumb_url', true )
    );
}
add_action( 'headway_after_entry_title', 'wpse66495_headway_title_button' );
