QB64 is meant to be a modern rewrite of Microsoft's MS-DOS QBASIC 1.1 and QuickBasic 4.5 that runs on modern operating systems. Outside a niche hobby community, no one uses QBASIC and haven't for many, many years. QBASIC was a half-decent learning language back in maybe 1994 when MS-DOS 6.22 was the latest version, and Microsoft actually included it as part of the operating system.
I'd actually recommend Ruby. It's a modern dynamic programming language and can grow with you. Look at tutorials like Hackety Hack. Eric S. Raymond, who wrote the Jargon File, recommended Python. JavaScript isn't a bad start either; take a look at Codeacademy.
