It's a nice idea, but not entirely practical - there are simply too many commands. And that's before you start combining them.
The closest things to what you are suggesting are probably the Unofficial Command Reference Guide and the Official Command Reference Guide, both available in the Editors Depot Tutorials section. It's always worth looking at both because each has stuff that is not in the other, and even when they overlap it gives you two different takes on the same thing.
And, as an inhabitant of the Editing: General forum I don't think I have ever seen a question that I would describe as stupid. Occasionally somebody posts a question which is well covered in the tutorials, in which case they are politely pointed in the right direction. (There has been the odd case of somebody re-posting before they have studied the tutorial thoroughly, which is rude.)
In other words, if you can't figure something out, don't be afraid to ask. That is what the forum is for. Answered questions get put into the FAQ in the Editors Depot, so that in future people with the same problem will be able to find the answer by searching the FAQ. There's already a lot of stuff in there.
