in the end I starte

This answer might help. Task Runners (Gulp, Grunt, etc) and Bundlers (Webpack, Browserify). Why use together?

...and here's an example of using webpack from within a gulp task. This goes a step further and assumes that your webpack config is written in es6.

var gulp = require('gulp');
var webpack = require('webpack');
var gutil = require('gutil');
var babel = require('babel/register');
var config = require(path.join('../..', 'webpack.config.es6.js'));

gulp.task('webpack-es6-test', function(done){
   webpack(config).run(onBuild(done));
});

function onBuild(done) {
    return function(err, stats) {
        if (err) {
            gutil.log('Error', err);
            if (done) {
                done();
            }
        } else {
            Object.keys(stats.compilation.assets).forEach(function(key) {
                gutil.log('Webpack: output ', gutil.colors.green(key));
            });
            gutil.log('Webpack: ', gutil.colors.blue('finished ', stats.compilation.name));
            if (done) {
                done();
            }
        }
    }
}

I think you'll find that as your app gets more complicated, you might want to use gulp with a webpack task as per example above. This allows you to do a few more interesting things in your build that webpack loaders and plugins really don't do, ie. creating output directories, starting servers, etc. Well, to be succinct, webpack actually can do those things, but you might find them limited for your long term needs. One of the biggest advantages you get from gulp -> webpack is that you can customize your webpack config for different environments and have gulp do the right task for the right time. Its really up to you, but there's nothing wrong with running webpack from gulp, in fact there's some pretty interesting examples of how to do it. The example above is basically from jlongster.
