Why do people have to e-mail you to get the files? Standard practice is to attach it to your post or host it somewhere so people can download it. If it's just a compiled AutoIt script it should be small enough to attach to a post.
Wrappers are always in demand, infact there is a page on the wiki
here where you can post links to download them. If you create a post and attach the file, add a link to it on the wrappers page in the wiki.
BTW You don't really need a wrapper for NEStopia AFAIK. To remove the menu go to View->Show->Menu / Dialogs. Also you can change the key to toggle the menu by going to Options->Input->View->Toggle Menu. You can also change the menu color to black in Options->Preferences.
