No.
But you're overstating the difficulty of "working with code". XML modding is basic database editing and is very straightforward to learn; for instance, let's say you want to make it take longer to chop down forests. (Changing sheep to not spawn on deserts can't be done in XML; that's a Lua change and is MUCH more complex. Resource distribution in general is a pain to alter.)
Here's the entirety of what you'd have to mod:
Code:
<GameData>
<BuildFeatures>
<Set Time="200"/>
<Where BuildType="BUILD_REMOVE_FOREST"/>
</BuildFeatures>
</GameData>
That makes the standard Remove Forest action for the Worker take 2 turns, instead of the normal 4. It won't, however, change the time needed for the auto-chop done when you try to place a Farm on a Forest, for instance. A more general version would be:
Code:
<GameData>
<BuildFeatures>
<Set Time="200"/>
<Where FeatureType="FEATURE_FOREST" Time="400"/>
</BuildFeatures>
</GameData>
The implicit "AND" in the Where command is necessary there, because the chop done when sacrificing a Great Person to place, say, an Academy on a forest the action needs to stay at Time=0. The above basically says "any build action that can only be done on a forest and normally takes four turns should be changed to only take two turns".
Once you do that small change, there's a tiny bit of overhead involved in configuring a mod to work. Go read Kael's modding guide, stickied at the top of the Reference forum, for a more detailed explanation, but the things to look for are the phrases "OnModActivated" and "UpdateDatabase".
--------------------
There are no visual tools for modding Civ5; while a few visual interfaces have been made by various people for specific parts (such as the tech tree editing), nothing general like you describe is or likely ever will be available, because the added flexibility due to using real programming languages comes at a cost of complexity. And if the above code just seems too complex for you to ever get the hang of, then you should just forget about modding at all, because it's just not going to get any simpler than that. (I'm not saying that you wouldn't have a learning curve; it DOES take a little practice. But it really doesn't take long to pick up once you get started.)
