While building a computer may seem overwhelming when you know nothing about it, it's not actually particularly difficult; not much different from, say, assembling a chair. Any case you get will come with clear instructions on how to attach all the parts, so don't worry so much about the assembling process. Removing your hard drive without damaging it should also be easy; it'd probably be harder to damage it somehow!
The programs you use are, in some ways, even more resource-intensive than AAA games. While games often need a powerful GPU, your primary bottlenecks are likely your CPU and RAM. You probably want a powerful CPU with multiple cores, and at least 32GB of RAM. A decent-but-not-top-tier GPU should be sufficient. SSDs are a standard nowadays and heartily recommended—using one will certainly improve loading times *very* measurably (seriously, you won't be able to go back to HDDs once you start using one)
There are a number of sites designed to help you build a PC, like [LINK]
You can of course also buy a prebuilt one if you'd rather avoid the hassle, just make sure to look at the specs for what you need. You could also round up some IRL tech guy to help you out (maybe your parents know someone?). There's no avoiding learning at least *something* about how computers work if you want to make sure you're getting what you need, but it shouldn't take a lot of time. If you have any more specific questions, you can of course also ask them here! I'm sure me and other people will be willing to help you.
