si se puede con javascript o php pero tendrías que leer los valores de las divisas desde algún sitio que los actualice diariamente (
http://www.ecb.europa.eu/ecb/html/index.es.html)
directamente del banco europeo, tienes que tomar el valor que te interesa limpiarlo y utilizarlo por ejemplo multiplicarlo por el precio en euros

<?php
//This is a PHP (4/5) script example on how eurofxref-daily.xml can be parsed
//Read eurofxref-daily.xml file in memory
$XMLContent= file("http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml");
//the file is updated daily between 2.15 p.m. and 3.00 p.m. CET
foreach ($XMLContent as $line) {

if (ereg("rate='([[:graph:]]+)'",$line,$rate)) {
//Output the value of 1 EUR for a currency code
