Integrate wordpress with front page - just want to display the last 10 posts on index.htm

<?php
include ('db_info.inc');
$con = mysql_connect($hostname, $dbuser, $dbpass);
$select = mysql_select_db ($selectdb, $con);
$query = "SELECT * FROM wp_posts WHERE post_status = 'publish' ORDER BY ID DESC LIMIT 5";
$result = mysql_query ($query, $con);
$number_rows = mysql_num_rows ($result);
if ($number_rows == 0)
{
$error_message = "No posts yet.";
echo ("$error_message");
}

else
{
echo ("<h2>Last 5 Blog Posts</h2>");
while ($row = mysql_fetch_array ($result))
{
// construct variables to capture post title, post content and guid (url)
// You may want to curtail the length of post content
}

echo ("
// Format the output using post title, post content and guid variables
");

}
?>
