If you're asking how to set up a Delaware company as a non-US resident without ever stepping on US soil, then yes, it's possible.

You can do that via an agent. You can find one by googling 'Delaware Inc' or 'Delaware LLC' or by looking at the official list of registered agents at http://corp.delaware.gov/agents/agts.shtml. It usually costs around $200-$300 per annum for the basic service.
