I'm not sure what the world needs most is yet another package manager,
but if you want some ideas you can take a look at the Smart project ?
It is currently written in Python, though, so it might not fit your
requirements. But it presents a GTK+ interface, on top of rpm and deb.
There's also a panel plugin, for displaying update status in the panel.
So that you know when there are updates available. It's over on Goodies.
Otherwise gslapt for slapt-get seems to be most like to what you want,
it's an interface written in GTK for a package manager written in C...
Or perhaps even look at the oldest of them all, the venerable Synaptic.
But it is written in C++, not C, so doesn't fit language requirements.

The biggest issue here is that the GUI won't have any extra privileges.
And normally you can't install/remove anything, without authentication ?
This is why a lot of the existing applications use a client/server setup
or something like DBUS to send messages from a frontend to a backend...
In the old days you would run the entire application with setuid/gksudo,
but that is not allowed anymore (being a security risk, running as root)
If you don't want to write such a setup, you might look into writing a
new PackageKit GTK GUI and providing a backend for your package manager.
The daemon is written in C (with glib/dbus), so would fit your language.
But the official graphic interfaces are very much GNOME and KDE only...
(I do believe there used to be at least some code examples using GTK+
but the shiny new 3.14 version is all GNOME 3 and systemd and similar)
Most users don't like it when you throw a terminal window in their faces
instead of a nice progress bar but even Ubuntu does it so it must be OK.
The Fedora Xfce spin uses Yum Extender in PyGTK for a graphic interface.
