Can you please let us know of the exact use case scenario you're trying to achieve, so maybe we can give you a more specific advice. Generally there is some difference between custom Sitefinity Content-based modules, and intra-site modules. The latter represent more of a convenient way of organizing your custom/user controls in Sitefinity backed, and require less programmatic effort and level of experience. Josh Morales has made a great post on creating an intra-site module for Sitefinity 4.x
, I believe you might find it useful. Along with this, the following webinar
also addresses intra-site modules, so you might want to take a look at it as well.
Content-based modules, on the other hand, allow for more cmplicated use case scenarios, and resemble the Sitefinity content based modules (e.g. News, Blogs) by allowing you to create a new content type, and implement all the logic including permissions, lifecycle etc. A great example of a complete content-based module can be found in our Sitefinity SDK - the products catalog sample. In addition, with the upcoming release, we'll be introducing the Module Builder tool, which will allow you to create content-based modules straight from Sitefinity backend. For a quick preview on the expected functionality, you might want to tkae a look at our roadmap
