Custom Python Software that can be used to customize triggered events, videos, audio, etc.

I'm working on an idea that involves software that enables the user to customize the order of their Tasks by preventing distractions and displaying short Tasks in any order. The user creates a Task (video, audio, text, image, website, dialogue) that will be triggered at a specified time or after a previous task. Display Video (regular or fullscreen) Play Audio (loop?) Show text or Images (at custom intervals) Display dialogue and input text Display a Website fullscreen. There needs to be a Settings section with the option to: Upload Multiple files at once (audio, video, text, images) Add/Remove Distractive programs, websites, audio or video. - Anytime these are opened, they'll be closed immediately Add/Remove Looping text, audio, video, images Add/remove text. Location to display (random, top, bottom, left, right, center) Text: Display every X seconds. Message Duration. Change Font, Size or Color Add/remove images. Location to display. Display every X seconds. Message Duration. Add/remove Audio. Time or Trigger event to play. Start play time, End play time) Add/remove Videos. Location to display. Start play time, End play time) Change intervals of text, images, audio or videos Add/remove Website. Sort the order of all Tasks defined by user by click+dragging up or down. - All tasks have a predetermined time to start or starts after the previous task is complete. Check/Uncheck Run at Startup Size of Window, regular or Fullscreen. Lock window on Top to prevent distractions or programs/videos/audio. This disables the use of Alt+Tab. Password to give control to a friend as extra security to example: lock the checkbox Lock Window and lock the checkbox of window to Fullscreen. Change Password - Reset password with the friend's email. Cross-platform preferred. Windows is a must. More details can be discussed with the chosen programmer.
