Perhaps GDB is looking in the wrong directory for your source files.
You can specify where your source files are using the `dir' command
(try `help dir', too).  I could help better if you gave us the exact
commands you used to compile your program and to run GDB.  Also, does
GDB output any error message when you say `list'?

You can debug Ada programs using GDB, but GDB by default does not
understand Ada syntax, and you won't be able to set breakpoints on
exceptions.  For these additional features, you need an Ada-aware GDB
available from http://libre.act-europe.fr/GDB.  If you are a Debian
user, you can also apt-get install gnat-gdb to get it (in unstable).

Others have pointed you to GVD and GPS.  Both are front-ends to GDB,
so you'll need GDB to work for you anyway.  Emacs also has such a
front-end.
