A Interface designer which produces code in C was something which I have
been searching for a long time. I found a application which I sense is a
Great Tool which enables Interface Designing in GTK+
Glade is a free user interface builder for GTK+
The user interfaces designed in Glade are saved as XML, and by using the
be loaded by applications dynamically as needed. (Glade can also
generate C code, though this isn't recommended for large applications.)
By using libglade, Glade XML files can be used in numerous programming
languages including C, C++, Java, Perl, Python, C#, Pike, Ruby, Haskell,
Objective Caml and Scheme. Adding support for other languages is easy too.

Search for "glade" in Synaptic and install, then ur ready to design
if the cache doesn't work you can install the 3 files attached here..
But you will have to learn a bit about programming in GTK to make full
use of this.
Lets Start making cool Interfaces..
All the best
