    var mapPanel = new GeoExt.MapPanel({
        border: false,
        renderTo: "div-id",
        map: {
            maxExtent: new OpenLayers.Bounds(-90, -45, 90, 45)
        }
    });

Sample code to create a map panel with a bottom toolbar in a Window:

    var win = new Ext.Window({
        title: "My Map",
        items: [{
            xtype: "gx_mappanel",
            bbar: new Ext.Toolbar()
        }]
    });
