You can learn anything in 4 months but not necessarily to the level where you're as effective as required.
Programming is 99% defining the problem and designing a solution, and 1% tapping your keyboard. Perhaps your problem is to learn enough programming to create a proof of concept of whatever you're wanting to eventually build as a real product.
Before you set off on your journey, it would be wise to look at your competition in the same space. I'd say your greatest threat is likely to be existing business intelligence tools that allow the users to write their own complex queries that reach into various real-time and batched data sets and surface them as beautiful widgets and dashboards, which they can then share internally or externally through security policies. Some even have an element of artificial intelligence to try and find patterns and correlations that would be valuable to a business.
StackOverflow is just the path of least resistance. There was a time when developers would just have framework or language books sitting around for reference.
The solution to both your problems is the same: advertising your product (either that financial widget or yourself).
If you learnt to advertise yourself effectively, getting a job as a self taught developer should be a breeze.
Conversely, if you learnt to advertise your financial widget so that it paid you a full-time salary, you could effectively hire yourself and continue building more products.
