Fly casting isn't as difficult as it may seem. Solid instruction and a lot of practice certainly goes a long way in forming good technique and habits, but the other key component is the gear you use to learn with. The fly rod is at the pinnacle of importance here, as a good rod with the right action can really speed up the learning process and help the novice feel the cast much better. But what fly rod action is best when just starting out?

Fly rod actions are typically classified as slow, medium, medium-fast, fast, and extra-fast. A slow-action rod is quite soft while casting, flexing deeply down towards the handle and offers finesse but not much raw casting power. On the other end of the spectrum, an extra-fast rod focuses most of its flex towards the tip for less delicacy but much more power and distance capability. Related to rod action is rod recovery, or how quickly a rod snaps back from bent to straight again. As you can imagine, a slow action rod has slow recovery because it flexes so deeply which means the tip has to travel quite a ways back to the straight position. On the other hand, an extra-fast rod under the same load will have much faster recovery since its flex is concentrated more closely to the tip.
The faster the rod action/recovery, the better your technique and timing has to be. On shorter casts, these rods also typically offer less feel to some degree because they just feel stiffer while casting. In my opinion, extra-fast rods should be avoided by beginners because they are really more specialized and require excellent technique for the best performance. Thankfully, many fly rod manufacturers don't hide this fact and market the fastest rods towards advanced anglers and difficult situations.
Fast-action rods are just a hair slower, but to me they are a lot easier to live with. This is perhaps why they are so popular these days. Good fast-action rods offer decent feel at close range, have ample power for casting far, can cast larger/heavier flies well, and are efficient at cutting through wind. For me this is my favorite rod action due to the versatility and the fact that I fish a lot of streamers.
If I had to choose just one rod action to learn on, then it would be the medium-fast graphite rod. The action is forgiving to the beginner but it's not so slow that it'll make it difficult to transition to faster rods later on. While not the most powerful or delicate action out there, it provides a great middle ground that works well in a variety of scenarios, too. If you want to fly fish for species like trout and panfish, a medium-fast rod might even be all you ever want or need, but it can definitely work well for all types of fly fishing situations.
With that said, I never discount the idea of a fast-action rod for the beginner. Some may disagree, but with the prevalence of these rods on the market, why not start off learning with one? If you plan on doing mostly heavier-duty fly fishing such as for bass, with streamers, in saltwater, etc, the fast action works very well. It could be argued that you can learn the basics on a slower rod then move up to the fast rod when your skills get honed (a good plan), but on the flip side you could save cash and start off learning with the best rod for the job. Just a thought.
Whatever route is chosen, I always suggest spending some decent cash on that first rod if you are absolutely 100% dedicated to learning fly fishing. The cost of some fly rods these days is absolutely sky high and I'm not necessarily telling you to go spend $900 on a new premium 5-weight (unless you want to!). I just don't recommend going ultra-cheap on some unrefined rod because that will NOT help you. Get something that has some quality behind it and feels right to you. The best part is, that'll be a rod you'll enjoy fishing with even after you move past the beginner stage!
