you can create unreal UMG dynamically without c++

in python you can access the widget tree following way

1. duplicate your userwidget from the template to make a new userwidget, and pass it to the next method
2. load the root node
   see unreal.load_object:
   first arg is the object’s outer, second arg is the object’s name.
   

   import unreal
   # given our user widget, we load the widget tree inside, which is a child of the user widget
   widget_tree  =  unreal.load_object(userwidget, name_of_widgettree)  
   # given the widget_tree, we load the rootnode, which is a child from the widget_tree
   root_node = unreal.load_object(widget_tree, name_of_rootnode)
   

3. add children to and save the userwidget.
   (this only works in unreal 5, not yet got it to work in 4)
