I would strongly recommend not doing this. The worst thing you can do when creating a piece of software is isolate yourself for x number of months and build it out entirely in isolation. I've effectively done this in the past, only to find out the product I built was not something people wanted to use.

If it's just for personal use, and/or you don't care about people using it, go for it. But if you care about adoption/traction, I would suggest surrounding yourself with people that may use your software, and constantly solicit their candid feedback (e.g. show them the software, but not tell them it's yours, etc...). Building software should be a collaborative process between you and your customer.
