I'm looking for a GUI drag and drop style GUI builder for Python Tkinter where I can create windows with forms, buttons, labels, etc. without actually writing any code. I would like the software to meet these requirements:

• Open source where I can use the software for commercial projects
• Compatible with Windows 10 64bit
• Uses latest Python (v3) & Tkinter standards and is an active project
