Search for a desktop single-user task manager (?) for windows xp sp 3

Question

Mobile development

The bottom line is this: so that I (the doctor) do not forget the dates of the next VC (medical commissions - extension of the disability certificate), ITU (... examination for a disability group), regular referrals of patients for research, a desktop application is needed to remind (notes on the desktop are not relevant) . Notebooks and leaflets have the most unpleasant property of getting lost or being removed to a place inaccessible to me by the orderlies of the department. There is a board with markers, but markers - see about books / pieces of paper.
The ideal option is an analogue of a task manager (timeline, deadline and other time points and whistles). Calendar for spreading the schedule of duty, consultations and departures for medical aviation.
Based on the features of the work, a product is needed that would not require access to the network (well, there is no Internet for smerds), would be single-user, would rustle on win32 and would not ask for money for work. Desirable - desktop (php-analogue does not want to raise).
And, I don’t have sclerosis and insanity, so far it seems, just work ... a lot. And Windows - well, it was at the workplace, I don’t touch it :)
Thank you.
