... And there are no other way to configure the kernel graphically,
This is not optionally, but the only possible choice.
I beleive that Qt must be active, you can also choose Qt (GPL), and
leave Qt (Commercial) for commercial
purpose, to maintain.
Tcl/Tk was and is GPL, and allow to recompile the kernel graphically.
Now, the choice
is Qt. Well, if you don't make changes ti the LSB, people are
configuring the kernel

qtconf.cc is NOT a commercial application.
Again, because actually is blocked because licenses, commercial
licenses, but Qt is also available under GPL,
you may enable Qt ... but Qt (GPL). And this means only the Qt when the
terms are GPL and therefore for free
This will solve the problem, I think.
