I need more information to help you choose the right way that will be suitable both for you and your users. Please answer following questions: 1) Do you expect users to try to bypass any restrictions you will put on them? In other words, do you expect them to try to create another Wine prefixe or try to do other "advanced things" to bypass your restrictions? If yes, any possible way to bypass such restrictions must be blocked (I will tell you how if you answer "yes" to this question). 2) Are programs you wish your users to use require writable registry access? 3) Are programs you wish your users to use require writable filesystem access? (For example, many web-based and some other programs don't require any kind of writable access assuming they are already configured). 4) Can you code in C? Can you write zsh/bash scripts? At least basic knowledge of C and zsh/bash scripting is recommended. However there is many things you can do even without any such knowledge - depends on what you want (answer questions above).
