Like Gtk, Qt can also work directly with an XML interface definition
file.  In Gtk, you can use the GtkBuilder class to parse a glade UI file
(which is XML), and generate the in-memory objects for that UI, and
interact with it just as if you had created it manually with gtk_*_new()
calls.

Likewise, Qt has something similar.  The equivalent to Glade is called
Qt Designer (often /usr/bin/designer or /usr/bin/designer-qt5).  It
creates .ui files that are XML similar to how Glade does it.  Qt has a
component called uic which translates the XML files into C++ code. But
you can do it dynamically at runtime, similar to GtkBuilder.  The class
is called QuiLoader.

Mind you Qt is a competitor for Gtk+ only if you don't want to code in C.
