Looking for tool (+plugins) for designing UI for _desktop_ application

Hi, I'm on a mission to find a tool for converting my pen and paper UI prototypes to more "cleaner" versions. I found tons of different plugins for Photoshop and Mobile UI designing, but none for desktop application UI designing. More specific plugin should contain UI components for Java applications (windows look and feel or something).

In the last job I used Photoshop where I had a set images of UI components which I copied to my UI design and then resized manually to correct size. It worked fine, but was a bit... unpleasant. So I'm looking for a easier way to do it. I need layers so I can do different views and UI panels on different layers etc. Resizing the components would be great and maybe even change the look and feel of all components from a menu.

Should I create a new UI component image toolbox for Photoshop and do it the old way or is there a easier way to do it with one of the Adobe's CC tools?

Cheers,
