What about LibreCAD (former QCad Community Edition)?
I also use gschem often without creating a board with pcb from the schematic, mostly to create schematics for pSPICE simulations.
I still believe that there should be a middle layer between gschem and pcb, to map the logical to the physical. A purely logical schematic file, a logical-component to physical-component file, and a purely physical board file for the actual PCB. The mapping file includes manufacturer, part no, pin mapping and footprint information. gschem doesn't store 'footprint', but 'component' attributes for parts, and pins have logical names which are used in the mapping file, instead of numbers. That makes it possible to have different boards (e.g. a 2-layer THT and and a 4-layer SMD board) made from the same schematic, or to make 10 different boards which just differ in the relays (and their footprints) used, etc.

Best regards,
Robert
