JQWicket - Modal/Dialog to an External URL, Or Something Like It?

Good afternoon everybody!

Can one point a dialog in JQWicket to an external URL (or just in Wicket in
general..)? E.g. can I have a link that opens a modal dialog showing
"https://www.google.com/" in it, or something like that?

I keep seeing this example over and over, but it's to some internal text
you've set up on the page rather than an external site.

Java:
final DialogWebMarkupContainer dialog = new
DialogWebMarkupContainer(
"dialog", new DialogOptions().modal(true).resizable(false));
add(dialog);

add(new AjaxLink<Void>("dialog.open1") {
@Override
public void onClick(AjaxRequestTarget target) {
dialog.open(target);

});

HTML:
TestExternal <br/>
<div wicket:id="dialog" title="Basic dialog">
<p>This is the default dialog which is useful for displaying information.
The dialog window can be moved, resized and closed with the 'x' icon.</p>
</div>

I'd appreciate any help greatly! Thanks!
