I would not use a kit. Kits usually come with mediocre equipment, something you would dump after you got the 'brew bug'.
Some of the equipment to start:
Siphon, few water jugs, a wine or a beer yeast, bakers yeast (as nutrient), any kind of sanitizer you feel most comfortable and depending on how clean your tap water is, an air lock and a bung or a grommet. A hydrometer and measuring glass, you can possibly also use that tube the hydrometer comes in as it, wine thief (optional), Diammonium Phosphate (nutrient, optional), any other kind of yeast nutrient (optional), sulfate and sorbate for stabilization (if your going to either back sweeten or age for a considerable amount of time), a milligram scale (0.1 accuracy).
If your water jug looks something like
this, you could drill or some other way make a hole to the lid and add a grommet, or buy a correct size bung. Some people have glued the airlock to it.
Netherlands probably has amazing brew stores.
Brouwland is also close, it's good for buying mead and wine making equipment and chemicals, and they probably have low shipping cost to Netherlands.
