vim has a GUI, too. And not a bad one. I think it might be really helpful to some people. Especially in the evim (easy vim) mode it should be no problem for the people to use it. It sets itself in insert mode automatically so people can use it just like notepad or such, with the added value of all that vim offers, of course:

• folding: You can collapse functions to just one line to improve readability
• syntax highlighting: There are syntax file for almost anything
• block mode: Especially useful if you want to comment out big paragraphs, just mark the lines as block, Insert a # infront of them and you are done.

And, vim for win32 has even an ole interface with which you can integrate in quite many programs directly. It was originally done for Visual Studio but can be used for other things aswell.
