Yeah that does happen with new users. So there are 2 ways of accomplishing this.
One
Instead of installing the usual Ubuntu, I'd suggest that you introduce to this user the other derivatives of linux. Any new OS, users will definitely encounter a slight learning curve. This cannot be brushed aside.
But the other derivatives of linux will still amaze anybody.
- Deepin - https://www.deepin.org/en/ - This OS, is absolutely fantastic. I've tried it myself, and being a developer and entrepreneur, my netting standards are quite high. I would suggest you try this out. There was however one issue regarding that OS when I tried it around 2 years back. I don't remember what it was, but I'd still suggest you try it.
- Linux Mint - linuxmint.com - This is a bit more like Windows XP. It's also a fantastic distribution, and has quite a long track record.
- Elementary OS - elementary.io - This too is beautiful. I tried it out properly just a few days back. And it's great. It's more of a MacOS replacement, although the official claim stands out as a "A fast and open replacement for Windows and macOS". *Type in a $0 as payment, and the Purchase button will change to a Download button.
There's many, many more linux distributions out there. The above few distributions are what I would recommend for a new user, switching through from any Windows or Mac OS, although I personally prefer the standard Ubuntu from Canonical. And even for new users, I would still suggest the standard. Once they get used to the realestate screen space, I doubt they'd not enjoy it.

Two
The other easy method of doing this to an already existing installation, is to install the Gnome interface over your Ubuntu installation.
You can use these two commands in the terminal:
sudo apt-get install ubuntu-gnome-desktop
sudo service gdm restart
Once that's done, logout, and login by selecting the interface at the time of logging in
Then simply tweak the Gnome interface, and get the bar on the bottom of the screen.
Here's a tute on that: How can I move the top panel to the bottom in Gnome 3?
All in all, any user who steps into the world of Linux, has stepped into a more secure, a definitely beautiful, and absolutely fantastic world.
There's always something more to know; More to love.
That's Linux.
