Hmm... this could be easily doable given how NickelMenu already handles selection menu stuff (getting the selection, adding an option to do something) and dialogs (text input), and Nickel abstracts dictionary stuff enough that it's easy to add additional html to the dictionary result. It'd just be a matter of putting the two together.
I don't have time to work on this right now, but it's definitely possible (~600-900 lines of code), and maybe someone else could work on it.
