Custom page – add content via php?

Hi guys,
I am running thesis 1.51 and I have a problem establishing a custom homepage (to implement a differnt sidebar).

So far:
I call up the homepage like this:

function custom_sidebar_01() {
if (is_Home() || is_front_page() || is_page('14'))  {
?>
<div id="content">
...

Later I get the sidebar like this:
<?php thesis_sidebar_2(); ?>

Now: how would I get the regular content via a php-function into my custom template? I have the home page saved as a static page already, so the content must be stored in the db somewhere.

On my static home page, the divs are:
content_box
content
post-14 class: post_box top
format_text

Thanks for any help!
