if($prod_qty==0)
{
     <?php
     <input type="button" value="Add to Cart" disabled />
     <?php
}

UPDATE 2 :

<input type="button" value="Add to Cart" 
  <?php if($row["prod_qty"]==0) 
  {
     echo ' onclick="addtocart('.$row["prod_id"].')" ';
  }
  else
  {
       echo ' disabled=disabled ';
  }
?>
 />

Add an if condition to the button to set the property as disabled if $prod_qty == '0' like shown below :

<input type="button" value="Add to Cart" <?php if ($prod_qty == '0'){ ?> disabled <?php   } ?> onclick="addtocart(<?php echo $row["prod_id"]?>)" />
