Create a sample part of a 2D game by cocos2d-x and C++

I need the source code of a simple app made by cocos2d-x and C++ which includes a 25x25 isometric tiled map with 64x32 tiles and a menu for selecting available sprites and let me to select an put them anywhere on the [login to view URL] should be a cross on top corner of sprites which let me delete the item from the map. I also should be able to select items from the map that occurs a simple movement (big&small, up&down, etc.) to show us the selection and let us move it on the map.
