You may be interested in (for example) the approach taken with Halogen, the PureScript web framework. Every widget on the screen has its own state and actions, widgets send each other messages, etc. It ends up being very "object oriented" in a way that you're suggesting, but it also is very principled, i.e. components send each other messages, do not have access to each others internal states, etc. This gives you a really good way to separate concerns, while having each "widget" have its own state/not having to have a single global state a la elm.
