cross platform word processing program containable in on a thumb drive, prefered in the creative commons license or equivilent

Very simple program nothing fancy. Text editor cross platform fully functional from a thumb drive. Text editor cannot edit, or delete text from the document, other programs cannot either. Auto stamp date/time at the end or each addition. Ability to strikethrough or ghost the deleted text, (ghost through preferred). Ability to add images once the image is added can not be removed, but can be ghosted, thumbprint image nice but not required. if easier each addition can be though of as a page in a journal and the document as a project. This document would be a living document being added to but never being deleted. nothing fancy GUI think notepad+ with the ability to add images, prevention of deletion and color code section that can be undone, and to be able to colligate the color coded sections to a single page. I have the idea from an engineers journal hand written and things added to the journal my penmanship is horable, I am studying to be an engineer, engineers hand hand written notes for each project that that they are working on graphs, charts, notes, etc. I want a program that can do the same thing, the most important thing is nothing can be removed from the journal, only things can be added, changes can be crossed out Timeframe: Several months
