You would need a "two stage approach".
1.
Create an ISO-9660 file system with a standard RockRidge extension.
This would allow you to master a file system for the CD or DVD which
is usually represented by a .iso file.
2.
You record this file onto a CD or DVD using the "data disc" settings.
Of course, K3B can do this with an implicite step 1 ("on the fly")
with no .iso file hanging around.

Do you think you can tell me what a "floppy disc" would look like? :-)
Don't confuse "disk" ("floppy disk") and "disc" (like CD or DVD).

K3B should be able to generate an ISO-9660 file system with the
standard RockRidge extension.
But if you do consider 3 lines of shell code "push-button", maybe
this is for you:
% mkisofs -r -o /tmp/kline.iso ~/kline
% cdrecord dev=1,0,0 speed=32 -v -eject -tao -data /tmp/kline.iso
% rm /tmp/kline.iso
Don't store the .iso file within the subtree you're recording, this
may lead to infinity. :-)
Of course, you don't need to use cdrecord. The burncd command or
cdrdao will do fine, too.
For a DVD, you need growisofs.
% growisofs -dvd-compat -Z /dev/dvd=/tmp/kline.iso
In my opinion, all this stuff is more "push-button" than trying to
find all the settings in a GUI application. :-)
As a sidenote, I just like to mention that you don't need to use an
ISO-9660 filesystem. Because we're on FreeBSD here, you can use any (!)
file system on a CD or DVD, such as UFS or tar (check advantages and
disadvantages).
