That's a problem. Seaside supports opening popup windows in two ways,
either with the target attribute

html anchor
    newTarget;
    callback: [];
    with: ...

or with JavaScript, which gives you more control

html popupAnchor
    callback: [];
    with: ...

See WAPopupTest for an example

both of them work only on anchors, basically because that how HTML and
HTTP work. Doing it with a button in a form and the form data would be
possible but requires some JavaScript. In general Seaside applications
have very little use for popups. You can easily put the content of the
popup window in a component somewhere on the page without distracting
or surprising the user.
