Why would you do that? Kentico generates *Info and *InfoProvider classes for each class in custom module, so why don't you want to use them?
If you haven't appropriate classes generated/available in your solution go to Modules in Kentico admin interface, navigate module you need, Classes -> choose a class you need -> Code. This will open code generating tool. You can change namespace and some other settings, click generate and save. It will save classes into a file system. Now add them to the Visual Studio and use them.
