Pick 1 spell effect from around the side of the screen, say fire and a fire icon appears around a cauldron/flask/crystal ball/frog . Pick another effect, say burden and a burden icon appears around the cauldron, next to the fire perhaps, or below or... Doesn't matter.
Beside each icon there is a vertical slider, this changes the base magnitude, the brightness of the icon changes wrt the slider.
Optionally the base duration of the effect could be selected by a horizontal slider below the icon. Maybe the icon gets fatter
The cost in gold and base mana is shown on the side of the cauldron.
best I can do at such short notice.

Good idea. When I think of non spreadsheet I always think live, while playing the game. I forget that no matter how pretty you make the skill page, it is still a spreadsheet, just not as functional
