So after some more retries and hair tearing, i understand that i 
unfortunately can't write anything for GTK in C from scratch, because i 
can't find any human-compatible logic in all information i read, in part 
of writing callback procedures. :/
Well, negative result is also result.
I will continue my work of course, in all places when possible, but most 
interesting (and most awaiting and welcomed) part, GUI writing, is weak 
and incomplete in my implementation, sorry.
Thanks;)
