Anyone here experienced on commercial software development?

So after finishing the whole concept of our program, me and my friends kinda stuck in developing the UI(User Interface). The program is a RAM optimizer tool, which we agreed to put on a PPI network.

We would like to ask for some experienced Commercial Software developer here for some tips in how to build the UI, currently here is our design(image attached) but it really seems empty, which we think that the users would not like. So besides from "Install" and "Uninstall" (or start or stop) buttons, what else could we possibly put in there to make it more "commercial"?

This is our first time developing Applications to be publicly released.

Thank..

Seems most appropriate to be moved to programming chat seeing as you are asking for the help of software developers.

Everyone else please note that the OP is asking for information and advice and not for paid help.

@franz119 if you would prefer to request paid help you can post in hire a freelancer forum or request the thread be moved there.
