Currently mainstream k8s is text based, because it's still too fast moving and new. Creating a great GUI would be a serious overhead and there's not enough interest/demand for it. It'll come eventually.
Rancher is even more approachable and streamlined than Openshift. Yeah we need k8s to be more streamlined. It's fragmented cluster-something right now. There is no pride in making systems more complex nor there is pride in knowing how to operate them.
OpenShift's web interface lets you do a lot (other alternatives are of course available). And it's quite nice being able to edit the YAML of everything via the web interface as well!
