We don't do modding on demand for people, we are all volunteers. If you want to change things you have to learn how to. As you have read it is not a trivial task to modify events; something in the region of many hours of work, and then the additional testing for many hours more.
I myself have spent many 1,000's of hours just getting familar with the RtW system and making minor changes via XML to create my mod, when it all looked greek to me too. I am still not confident enough to code the python scripts, let alone the DLL code, which is still greek to me, albeit I have made minor changes by simply commenting out sections I did want happening like some hard winters.
If you are motivated enough to change it (as it sounds like you are), I suggest you concentrate hard and work out what you need to do. Once you have learnt how, it will be like a light-bulb going off.
