I am not sure what you are trying to do.
Admin links can be conveniently created with admin_url()
function, like this:
$path="admin.php?page=wpsc_product_seo_details";
$url = admin_url($path);
$link = "<a href="https://wordpress.stackexchange.com/questions/4677/{$url}">Edit</a>";
echo $link;
What exactly do you have problem with?
