I'm sure you could manage to do a lot of things without a terminal on something like Fedora or Mint, but you really should just learn to use the command line. If you're expecting it to be anything close to the windows command line it is not, it's way easier to use and you'll be able to do things so much faster than you ever could with a gui on windows. Learning everything you really need shouldn't take more than a couple hours.

The one other option I can think of is ChromeOS Flex, but even there you're going to have a way better experience if you learn to do things from the command line when appropriate
