I don't run a web hosting company, so my explanation will be less technical and from the perspective of a client.
WHMCS is a software used by web hosting companies to support and bill their clients. The software can also be automated enough to run your whole operation (from provisioning servers, sell domains to answering support tickets).
WHM is the back-end software of cPanel (which is a popular control panel). The access to one is often given to clients of reseller hosting, because they are able to use it to add/remove clients, setup their own packages and perform other administrative tasks.
A control panel is an easy to use software that is usually given to clients of web hosting packages in order to have an easier way to manage their hosting account: setup email accounts, update their website, check website statistics, etc. The most popular control panel is cPanel, but Plesk and DirectAdmin are also frequently used.
