I’m trying to program a song using note frequencies and when I look up the notes they are all major (like C which has a frequency of 261), but then in the music sheet there are major and minor notes and I don’t know the difference in Hz. I should also say I don’t know anything about music and I don’t really grasp the concept of chord and note and the difference between them.

A singular note is neither major or minor. An A440 in A-major or A-minor is *always* 440hz.
Major and Minor refers to scales: the selected set of notes that make up the core of your song and the intervals between them. So the C-major scale is formed from C, D, E, F, G, A, and B. The C-minor scale is formed from C, D, E-flat, F, G, A-flat and B-flat. Note that the C used is the exact same C with the exact same frequency: the other notes you use have changed and that’s what creates the minor-sound.
A chord is when you play *multiple* notes at the same time. So C,E,G played at the same time make the C-major triad chord.
Generally you probably should find an intro to music-theory before trying to make your song just to get a grasp on the core concepts of musicology. It makes composing that much easier if you’re aware how the techniques and systems you’re trying to use work
