You have to decide what you want to do. Do you want to make ever more complex golang code and you will judge success by the complexity of the code and you're ability to get better with golang? Do you want to make something other people will use? Do you want to make something other people will buildon? You've put too many rules/restrictions and you really only want to work on the fun part but then you judge yourself harshly for not finishing to some state you haven't defined. A good business idea might be mostly frontend. The tools don't matter when you your goal is a successful product. Using golang or javascript is not important. A great business idea that must be implemented using mostly golang backend code that will stretch you as a developer where you can just work on the fun parts is like winning 3 lotteries at once.
