Something like this:

        private var dgArray:ArrayCollection =
            new ArrayCollection([
               { name:'One',
                 children:
                 [ {name:'Two'},
                   {name:'Three'},
                   {name:'Four', children:[{name:'Five'}, {name:'Six'}]},
                   {name:'Seven', children:[{name:'Eight'}]},
                   {name:'Nine'}
                 ]
               }
            ]);

Its actually pretty easy, you see, an Array, can have anything inside it, and to define an array inside another one you can just do this "[ parameters ]" that is the same that "new Array( parameters )"
so:

var array:Array = new Array ( obj,[obj2,obj3,[obj4,obj5]]);

this is the same that

 <mx:Array id="arr">
        <mx:Object id="obj1">
            <mx:children>
                <mx:Array>
                   <mx:Object id="obj2">
                     <mx:Object id="obj3">
                      <mx:children>
                            <mx:Array>
                                <mx:Object id="obj4" />
                                <mx:Object id="obj5" />
                            </mx:Array>
                        </mx:children>
                </mx:Array>
             </mx:children>
    </mx:Array>
