To be honest, it's not that difficult, but it's a different paradigm to what word processors have hammered into us. Ironically, word processors started as the glorified typewriters of the digital age, but scope creep led them to include more and more formatting (and other) features, to which they were ill-suited and the features ill-implemented (the hideousness of styles and themes in Word is truly breath-defying). As a result of trying to do everything they became not very good at everything but everyone is forced to use them, it's like trying to bash in nails with the handle of a screwdriver. Those people sobbing and holding clumps of their own hair in the corner of any office in the world? They're the ones trying to place an image in a Microsoft Word document.
The alternative takes a bit more planning to set up a document with margins, columns etc. and decide on a few styles (headings, body text). Then it's a case of drawing frames and adding the content, adding your styles to it, but that's it. They're composition tools (though you can, of course, edit and write text in them). The results not only come out looking vastly more professional, it's vastly less frustrating than trying to achieve the same results in a word processor. If I want a picture to appear right there, I put the frame where I want it, and that's that. It doesn't suicidally leap over the bounds of the page when I change something four pages downstream. And once set up, you simply use the same going forward, just change the content for each issue.
But yeah, there's a learning curve that you may or may not be inclined to.
