It's usually easiest to form your business where you are located, at least at first.
You'll find it's far easier to deal with only one countries tax system as opposed to having to pay a registered agent in an offshore location, having to file taxes in both the Netherlands and in the foreign jurisdiction where you form your business. And that's before we get into the hassle of foreign bank accounts so your foreign business can operate (in other words, plan on traveling to the country where you establish your business to take care of some things).
Form your business locally. VAT rate in the Netherlands is 19% and you won't have to worry about collecting VAT until your sales exceed €104,369 anyway.
Since you aren't physically exporting anything (presumably your electronic files will be downloaded and not shipped on cdroms), you won't need to worry about paying any kind of taxes in the UK or the US unless you establish a presence there.
Long story short: don't worry about trying to evade taxation until you actually have a decent income
