why not buy something like tyrannobuilder for relatively cheap and have a play around with the default characters/objects or find some free pre-made ones online and import them.
tyrannobuilder has a drag-and-drop interface that makes it a lot easier for the basic stuff at least.. makes it easier to get the hang of the whole overall process and the format of the production before jumping in the deep end and learning the language of these types of softwares and paying a lot more
