Yes it is possible. I never need the terminal. If you are interested, you can usually find a GUI way if you look for one. Some people just don't look, then tell people there is no GUI for it. Not very helpful for newbies.
For those not into usability, different people work in different ways. Visual workers are not the same as text workers. So for some, CLI has poor usability and productivity. For lots of things I do, there isn't a CLI anyway.
I use Kubuntu these days. It could be better.
