The Kernel is generating a process with the PID1 owned by root, assiciated with /dev/tty1 and starting init (look in linux/init/main.c/init(). If you use initrd, the Kernel will execute /linuxrc.
The best way to make a xterminal out of a linux box is to start the X-Server from the inittab, the second best is to replace /sbin/init with a program/script that handles all sysinitialisation and then executes the X-Server.

Its very easy to do that in Userspace, there is no need to reinvent the wheel. If you dont run a getty, there will be no consoles the user can switch to. You can then genrate manually.
