There are serebarl RUnge Kutta solvers.

Or try a search for either of the following

Runge Kutta rk23
Runge Kutta rk45

and of course there are textbooks.

Most good numerical methods textbooks will include the essential theory
plus a simple code, alays a good starting point before being exposed to
the more comprehensive coding appraoch found in the rk23/rk45 families.
