Hey - I just recently wrote a series of blog posts of creating a startup in the US and UK for developers. It's based on my experiences. If you're based in Europe being a UK based limited company is a great option. As others have said you'll need a good accountant and lawyer, the posts cover my experiences with various companies. Personally I'd recommend Crunch.co.uk for helping with the company formation and accounts. Then Lawbite for the legal side of things. They've answered a bunch of my questions.
One big thing to beware of is VAT and VAT MOSS scheme - it's a bit of a nightmare to figure out your way around that. After discussing with accounts and lawyers your best option is to not be VAT registered until you know you're going to exceed the £82k threshold. Again - speak with your own lawyer and accountants on this as everyone's situation is different.
Hope that helps!
