comment form challenge?

I need to make a new comment form to allow comments to be submitted from the main page, and inserted into the database. I don’t have a standard loop, which complicates things. As it stands, I have the various forms appearing after each post on the main page, but when I click submit, it just goes to a blank screen, trying to insert into wp-comments-post.php I assume. Here is my index.php, look at the form section I pulled from a typical comments.php file:

<?php
get_header ();
?>

<div id="box">

<?php

$qry =  "SELECT u.id, user_nicename, post_date, post_content, post_title, post_type, post_excerpt, comment_content, comment_author, comment_approved, comment_count, wp_posts.ID as post_id
         FROM wp_posts
         INNER JOIN wp_users AS u ON post_author = u.id
         LEFT JOIN wp_comments ON wp_posts.ID = comment_post_ID
         WHERE post_type='post'
         ORDER BY user_nicename ASC, post_date DESC";

$res = mysql_query($qry);

if ($res) {

    while ($row = mysql_fetch_assoc($res)) {
       $author[$row['user_nicename']][]=$row;
    }

    foreach($author as $k => $v) {
        $orderbydate[$v[0]['post_date']][$k] = $v;
    }
    krsort($orderbydate);
    foreach ($orderbydate as $k => $v) {
        ksort($orderbydate[$k], SORT_STRING);
    }
}

$divIds = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine');
$i = 0;

foreach ($orderbydate as $date => $authors) {
    foreach ($authors as $author=> $posts) {

          echo '<div id="'.$divIds[$i++].'">';
               if($author=="tony") {
                    echo '<img src="http://www.hippievstony.com/wp-content/uploads/2009/12/tonyname.jpg">';
               }
