[jQuery] jQuery OOP Question - Need Suggestions

[real]

Hi all,

I found a few threads related to jQuery OOP, but since I'm pretty new
to OOP maybe I just was not understanding a few things.

I pasted some code below, and it's my attempt at OOP, but is there a
way to make this code more jQuery like? Or just better in general? All
suggestions are welcome.

Thanks.

function jsWindow (opts){
        var settings = $.extend(
                {
                        title: 'Window',
                        width: 400,
                        dialogClass: 'jsWindow'
                },
                opts
        );

        this.width = settings.width;
        this.height = settings.height;
        this.title = settings.title;

        var self = this; // reference to object
        var $self; // will be used as reference to jQuery HTML element upon
this.create.window()

        this.create = {
                window: function(){
                        $window = $('<div></div>');

                        $window
                                .addClass(settings.dialogClass)
                                .css( { width: settings.width} )
                                .append('<h2></h2>')
                                        .find('h2')
                                        .text(settings.title)
                                .end()
                                .append('<div></div>')
