The easiest is the creation of simple interactive exercises which does not really require the knowledge about a computer language, but exercises that can be written in this way have limited power and versatility.
On the other hand, you can also develop full-power WIMS modules by working entirely on line. For obvious security reasons, you will need a login/password pair which you must ask the site manager to attribute to you. Once logged in, you can create and modify as many modules as you like, in a special development zone. When you have finished the development of a module, you can ask the site manager to move it to a public place.
