Thanks that helps, doesn't look like any of those GUIs include sliders. 

If I code something like that slider in Python will it be able to pop up just by running the python script with Alfred?

I'm not sure where to start with this and was hoping for some advice. I'd like to be able to quickly display (and then dismiss) a slider that can be adjusted through scrolling which adjusts something like display brightness. The volume adjustment slider in the menu bar on a mac has the behavior I'm looking to simulate.

I'd rather stick it into a workflow rather than code a separate app since Alfred is always open. The only thing close to this I've noticed is that the Packal Updater workflow somehow loads a window running php. 

If anyone has an idea on where I could start I'd appreciate it.
