I see two ways to do this:

1. CustomTreeCtrl has a method called SetItemWindow, you can use it to
associate any non-top level window to any item in the tree. In your case,
you can assign an AnimationCtrl which will play your gifs .

2. If you can split the gif into its composing static images, you may add
all those images to the CustomTreeCtrl wx.ImageList and then, in a timer,
call SetItemImage on the item you wish to have your gif “played”.
