Configuring GTK applications' appearance in Kubuntu

[Dotan Cohen]

How can the user can configure the appearance of the GTK applications
in Kubuntu? I do not have Gnome installed, though I suspect that in
Gnome there would be a System Settings application to configure GTK
appearance. Is there a text file that I can edit, or a GTK-appearance
application that I can install?

Thanks in advance.
