Maybe this helps as a starting point: Gulp/Kirby StarterKit (plus optional Docker support)
It certainly doesn’t make sense to use Gulp and Webpack in conjunction, because these tools basically do the same stuff, i.e. concatenate and minify etc. your assets.
Also, imo it’s no different if you use these tools with Kirby, plain HTML templates or any other CMS, the procedure will always be more or less the same.
