yes, try
var list = [{name: "Kansas", id: 1},{name: "Arizona", id: 2}];
var selectBox = new qx.ui.form.SelectBox();
var model = qx.data.marshal.Json.createModel(list);
var controller = new qx.data.controller.List(model, selectBox, "name");
this.getRoot().add(selectBox);
selectBox.setModelSelection([model.getItem(1)]);
For a dynamic application check this example and thread

But I just realize this alternative dont work:
var list = [{name: "Kansas", id: 1},{name: "Arizona", id: 2}];
var selectBox = new qx.ui.form.SelectBox();
var model = qx.data.marshal.Json.createModel(list);
var controller = new qx.data.controller.List(model, selectBox, "name");
this.getRoot().add(selectBox);
controller.setSelection([model.getItem(1)]);
Why dont work?
