You could assign an onsubmit event handler to the form to call a function which pops open a new window when the form is submitted and targets the form to that window, like:

<form action="..." method="post" onsubmit="some_popup_post(this);">
<!-- form fields etc here -->
</form>

And js code would be:

function some_popup_post(form) {
    window.open('', 'formpopup', 'width=400,height=400,resizeable,scrollbars');
    form.target = 'formpopup';
}

Do you mean something like this..
