I would like to add a button to this toolbar, right of "fullscreen":

enter image description here

The button should add this: „“

If text is selected, it should get around the text, like this: „selected text“

How can I add such a button to the ed_toolbar (class: quicktags-toolbar)?

Try adding the following code in your function.php

add_action( 'admin_footer-post-new.php', 'wpse_64665_add_quick_tag' );
add_action( 'admin_footer-post.php',     'wpse_64665_add_quick_tag' );
function wpse_64665_add_quick_tag() { ?>
    <script type="text/javascript">
        edButtons[edButtons.length] = new edButton( '„“', '„“', '„', '“', '' );

The new, recommended way to add buttons to the toolbar is via the Quicktags API. Furthermore the site GenerateWP provides a handy code generator, which for this example creates the following:

// Add Quicktags
function custom_quicktags() {
    if ( wp_script_is( 'quicktags' ) ) {
    <script type="text/javascript">
    QTags.addButton( 'fancy_quote_button', '„“', '„', '“', '\"', 'Fancy quotes', 9 );
add_action( 'admin_print_footer_scripts', 'custom_quicktags' );

Note also that QTags also allows you to call JavaScript from buttons; the simplest example given is:

QTags.addButton( 'my_id', 'my button', my_callback );
function my_callback() { alert('yeah!'); }
