Just provide COMBOBOX to CreateWindow() as the class name instead of your own precreated class, unlike you usually do when creating an overlapped window.

When Windows starts, it creates the system global classes for all applications. These classes contain the following familiar standard controls:

• Edit
• Listbox
• ComboBox
• ScrollBar
• Button
• Static

Example:

HWND CreateWindow( "COMBOBOX",
                   "Default String",
                   style,
                   x,
                   y,
                   width,
                   height,
                   parent,
                   menu,
                   instance,
                   Optional Parameter
);

Here they seem to go deeper with explaining.
Here you can also find info on possible combobox styles.
Sorry for the quality of the material on the links, I have just googled them up and didn't look through them too thoroughly.
Cheers.
