The current port of transmission to Haiku is a cli only app. This task is to add GUI interface to it using the Haiku API. To do this task you will need to install Haiku either in a VM or on real hardware, you can get familiarity with the Haiku API as well.

You can use the old Transmission GUI as base for your work and optionally take the second part of the task. The aim for this part will be a working GUI for basic actions.
