What's wrong with mkfs.<tab-tab>[select-middle-click] /dev/sdc1?
I love (and usually prefer) the Unix way, but it's as dangerous as it's powerful and the amount of the required prior knowledge is incomparable.
Moreover, the GP mentions "as a kid" which is probably at least 10 years ago, when the choice of GUI tools and their availability in various distros and their repos was much more limited.
Knowing that "mkfs" is a thing or that "/dev/sdc1" is a thing pushes the minimum knowledge requirements orders of magnitude higher.
