One lesson I learned and experienced from "both sides" is that you should avoid to ask difficult questions - difficult in term of how much effort is required from people who could help you. My advice is that you get into HTML / CSS (basics), javascript / jquery (actions, effects, …

You can use one of the game engines (Unity3d, UDK etc). You would still need a lot of work to do and to go into coding (depending of what you want to accomplish), but nowadays they definitelly make the game creation a lot easier and faster, even for non-coders.

you can also try jquery plugins, especially if you want some additional functionalities and styling beside randomizing images on load.
