Using hbox, vbox, and tables within Glade should give you a good idea
how they work and how to use them I think. They are not complex, even
for simple GUIs. Get familiar with how the various packing flags work
(expand, fill, pack type). And you feel free to use several kinds of
nested packing managers. It's not uncommon to have an hbox inside of a
vbox inside of an hbox, for example.

Glade does support the use of GtkFixed, but I highly recommend avoiding
the temptation to use it. It's there because there are the occasional
cases where you need pixel-perfect placing, but you should never use it
for general GUI use. Why would you want your GUI to not be able to
resize or adapt to HiDPI screens? I think Visual Studio and Windows did
us all a huge disfavor promoting fixed layouts. There's simply no need
for them. I've yet to see a layout that didn't work with a combination
of vboxes, hboxes, and table layouts. If you posted a fixed layout, I
would be willing to show you how to do it with a dynamic layout.
