i haven't tried this, so i dunno if it will work, but being as it is using javascript it may do the job..
<script type="text/javascript"><!--
google_ad_client = "pub-XXXXXXXXXXXXXXXXX";
google_ad_width = 468;
google_ad_height = 60;
google_ad_format = "468x60_as";
google_ad_channel ="XXXXXXXX";
google_color_border = "336699";
google_color_bg = "FFFFFF";
google_color_link = "0000FF";
google_color_url = "008000";
google_color_text = "000000";
//--></script>
<script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js" target="_blank">
</script>
replace
<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js" target="_blank">
</script>
with
<script type="text/javascript" onClick="window.open('http://pagead2.googlesyndication.com/pagead/show_ads.js','mywindow','toolbar=yes,
location=yes,directories=yes,status=yes,menubar=yes,scrollbars=yes,copyhistory=yes,
resizable=yes')">
</script>
but i think this method is used in a form function with a button.. so it may need altering slightly
