You don't actaully need any fancy wrapping.. just open https://script.google.com/ you can already access all google's APIs + you will be able to integrate your sheets with your gmail (send email), calendar (you can modify the calendar when the sheet get changes), create pages, allow inputs from form and etc..) The problem with that is the sheet will not have any .. transaction based ops like a real database so for example you want to lock certain resources.. you may fail..
