You will need to set a Static Page as your front page, create and assign a PHP Template for that page, and stack multiple Queries in the template to search out your required categories and display them. Here is one, you might have many:
// get the last post (any date) from 'Featured' category
$featured = new WP_Query( 'category_name=Featured&posts_per_page=1' );
if ( $featured->have_posts() )
{
while ( $featured->have_posts() )
{
$featured->the_post(); // fill $post with data
?>
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
<!-- output markup and display the post(s) -->
</div>
<?php
}
}
rewind_posts();
// start next query
That should give you an idea, at least, there is a fair bit to it. Good luck.
