    The way i got this to work is as follows: i wrote a jsni method to open a new window 

    public static native BodyElement getBodyElement() /*-{
        var win = window.open("", "win", "width=940,height=400,status=1,resizeable=1,scrollbars=1"); // a window object
        win.document.open("text/html", "replace");

    i added a basic body to the new window and returned the body element

    win.document.write("<HTML><HEAD>"+css1+css2+"</HEAD><BODY><div class=\"mainpanel\"><div style=\"width: 100%; height: 54px;\"><div id=\"mainbody\"class=\"mainbody\" style=\"width: 100%;\"></div></div></div></BODY></HTML>");
        win.document.close(); 
        win.focus();
        return win.document.body;
    }-*/;

    i then called this method from my main java method

    BodyElement bdElement = getBodyElement();

    I then injected my panel which has lots of widgets into the returned body element

    SystemConfiguration config = new SystemConfiguration();             bdElement.getOwnerDocument().getElementById("mainbody").appendChild(config.getElement());

    I agree with Bogdan: Use a DialogBox.

    If you can't, you Window.open() as you mentioned in option 1:

    1. Create another GWT module, and form.html that will load it
    2. Window.open("form.html?entry=54")
    3. Have the form gwt module read from the URL, load the entry, allow it to be edited, and provide Save and Cancel buttons
    4. Close the popup when Save or Cancel is clicked

    Can't you just use a DialogBox?

    Example
