Hmm, difficulty is relative. Some wikis have at least one person who is their basic js and/or lua coder. Then learning some AWB with a manual shouldn't really be that difficult, but understandably, not every wiki can afford that. For a bot like that you probably should have decent knowledge of logic, wikitext, and preferably regular expressions.
