I assume by which you mean "easy", you are referring to the GUI frontend installer of manjaro and mint, yes? In that case I'm very pessimistic that obarun would get a gui to install it. If an observer needs something more hands than systemd, It should already be assumed they are comfortable with the terminal. As I understand Manjaro hasn't entirely removed systemd completely because they have systemd-sysvcompat for qt5 among other things[0]. The only known Distro that has
nearly removed systemd with a gui is devuan.
The same assumption goes for the front page of the obarun website:

Obarun is not designed with beginners to Linux in mind, but it can be used easily with some basic knowledge.
Furthermore considering the development for a gui is mainly dependent on either gtk[1] or qt, I wouldn't think it's the best idea to depend yet another application on either, because gtk is a dependency mess and qt4/5 depends heavily on dbus[2][3]. Even if it was to just install to install the system "easier". For instance Manjaro{,-openrc}s install is dependent on gtk3, (webkitgtk3?!), dbus and systemd! [4] However, FLTK on the other hand is system-independent and doesn't depend on stupid things. So If there is ever a gui-frontend for some reason; I propose it to be in FLTK, less hassle and easier to clean (Although as a side affect fltks UI also looks like NeXTSTEP). But it's more practical (and sane) to not make a gui at all :)
As a side note of terrible dbus implications, this quote from cat-v goes along well.
