Considering that the software is open source and with a GPLv3 license, I would recommend PySide6 · PyPI as a mature, well maintained and powerful multiplatform toolkit. It is also a toolkit that the RSE team is familiar with, so we can better advise if/when needed.

There is also an excellent guide on developing PySide6 applications, Create Python GUIs with PySide2 — Simple GUIs to full apps, which also includes a section on embedding and interacting with Matplotlib plots into the application. This will be needed in all across Bubble Analyser when displaying the images, the result of the analysis and, naturally, when performing the calibration when the user will need to click on the images to define the pixel size.
