I personally don't know any programming languages...yet so I can't help you make the mod. However I can tell you that the way to do it would be to find the property of cactus (seeing as it's a solid block) that makes the upper cacti fall when the bottom is removed, and give that property to wood logs, oak, birch, and cedar. I believe this is how 500 ISE made his mod for Android in 0.5.0. I think he called decayed or rotted trees.
