How can I get started in modding Shandalar?

Ahoy there folks. I have been enjoying playing Shandalar over the last few months, using CirothUngol's "Shandalar 2012 revisited".
So I am now wondering how can I mod Shandalar myself? Examples of things I would like to mod would be:
I have barely any programming experience so I understand I might be out of my depth. But I would love to give it a try! So if anyone can tell me how to get started or can link a guide, I would really appreciate it.

So I am now wondering how can I mod Shandalar myself? Examples of things I would like to mod would be:
- Adding new cards. Not thousands, just the rest of Legends/The Dark and adding Fallen Empires, maybe Ice Age and Homelands.
- Changing Dungeon reward cards.
- Allowing you to gain Manalinks from 'defeat a monster' quests.
