changing space between dialog buttons?

Hi,
How would I increase the spacing between the buttons generated using
jQuery?
pseudo code...
$("#mydialog").dialog({
bgiframe: true,
autoOpen: false,
width: 600,
modal: true,
buttons: {
"Button Two": function() {
$(this).dialog('close');
},
"Button One": function() {
$(this).dialog('close');
},
close: function() {
}
});
Thank you lots in advance!
Scott
