If you can provide prepared workspace with transparent VCS-usage, they will use VCS. Don't teach non-programmers to use BCS in programmer's way

Just find editor with embedded VCS-support, configure it and show additional easy steps in their works.

Just an example - Editplus knows about Subversion, have ability to perform basic SVN operation inside editor window. Latest Editplus even can use TortoiseGIT for Git-integration

Edit: found some-way-alternative solution: EasySVN, which, being properly configured, monitor working copy and perform autocommit and automerge, allowing to use any authoring tool for end-user and any document's formats
