macOS Applescript Studio Cursor issues?

I have started building a Keyboard interface using Cocoa and Applescript Studio, Apologies if any of my syntax is wrong as im new to it. Anyway im setting it up to run on a second monitor which is touchscreen, Is there anyway I can make certain the application always opens on the touchscreen which is smaller than the main display im using (so specifying go to screen with such resolution may work if possible). And is it possible to press the buttons in the app which out the cursor jumping to that screen. I would if possible like the cursor always to rest in place on button press.

Another question can I make an application sit on top so it's always in front of other open windows?

Thanks
