I see phatch is a python package, so I think a little trick could be
possible:

%package cli:
BuildRequires:	python-devel
Requires:	non-gui-dependencies
%files
{_bindir}/phatch

and for the main package:
Requires:	phatch-cli
Requires:	pygtk2, <gui-dependencies>
[install desktop file etc...]


This way users could explicitly install phatch-cli, and it would "only"
not start up properly if called without arguments on a terminal, and the
main package (gui version) would contain the program and pull in the
graphical dependencies.
I don't know the program though, and if the cli version depends on gui
libraries to work properly as well it wouldn't work.
