Those would be my best tips. But if it is just you, don't expect results in months!
Then I would perhaps create a google docs/spreadsheet to lay out your idea of a game and kinda start from there. THat way, you can put it in a text form of what is happening at that point in the game, then the sheet can include the different aspects, etc.
Just a way to organize before diving in will make the process go faster
I dont know anything about computers or code ...I just want to say "Go for it"...you can do it.
And reaching out to network with others is a good idea and writing everything down. (always good to have proof of your ideas in case there is ever an issue)
edit: I have a few friends that I'm going to ask if they have any ideas, suggestions, or websites I can share with you.
