Thank you.
In a nutshell, I need to place components, lines, rectangles/circles/shapes, cutouts/boundaries, holes, vias, etc., on top/bottom layers, be able to group and move them as needed, then take the resulting layout and generate a Gerber file.
I do not want to generate a schematic and have the software route for me, as I focus on RF/analog design where layout is often more detailed than the corresponding schematic.
