How to sort data from Mysql table by month

Hello there,

I have created a PHP page that retrieves two columns from a MySQL db (date and amount). What i can't seem to comprehend is the next step... how to sum the amount and show it by month name and year as below.
The Mysql table i have consists of three columns:

-ID Autoincrement
-Date Date
-Minutes Int(11)

This is how i would like to have the data.

January 2001              45673
February 2001            34455
March 2001                23747
April 2001                  86464
May 2001                   6363
June 2001                   0
etc..

Here is my PHP code so far...
----------------------------------
<?php
// connect to the database
include("../include/irm.inc");

$query = "SELECT Date, Minutes FROM tbl_Minutes ORDER BY Date";

$sth = $adb->prepare($query);
if($sth)
{
        $res = $sth->execute();
        $numrows = $sth->rows();
        for($i = 0; $i < $numrows; $i++)
          {
                $result = $sth->fetchrow_hash();
                $Date = $result["Date"];
                $Minutes = $result["Minutes"];
                PRINT "$Date  ";
                PRINT "$Minutes <BR>";
         }
        $sth->finish();
} else
{
    PRINT "Could not prepare query: ".$sth->errstr."<br>\n";
}
?>
------------------------------------------
Any pointers, ideas or examples would be greatly appreciated. Thanks alot.
Richard.
