By single screen do you mean creating a snapshot of what the product should look like?

I was thinking about developing a really basic version of my product. I think having something tangible makes it easier to convince a good technical co-founder to join or to even get an investment.

I dont think that learning programming would be the most efficient way to spend my time. By the time I would get to the level I could create my application, the wave will have already passed. Furthermore, not everyone needs to know how to code, everyone should focus on what they're good at. I am good with sales, marketing, finance, and building websites. This of course puts me in a disadvantageous position when wanting to launch a startup.
