I don't think so. It shouldn't be much different, if at all, from any other template. You just have to keep in mind that the content will only be about 300px wide as opposed to a full page width. If you want an example... Do you see the "Upcoming Discord AMAs" section in the right rail here on this wiki? That has been added using AddRailModule. The template they used is MediaWiki:DiscordAMA. Of course, the name of yours will have to be Template:RailModule unless you have custom JS available. However, the type of stuff you can do is similar.
