First off all if you struggle with the C and G chord drop them for later, start with A and D and E but use this alternate fingering which I use already for about 40 years ( long fingers to )

A chord middle on 4th string 2nd fret, index on 3rd string 2nd fret and ring on second string, advantage of this fingering is that to go to the D chord the index stays in place ( only moving 2 fingers ) and to go from A or D to E you slide your index back to 1st fret and move only the other 2 fingers. Once you've got the hang of this then look at the C and G chord.
