You have to create a separate window, just like you do it in your WinMain().

You already have! Just copy and set it up for the second window (to be clear, code in both functions). And then, instead of calling MessageBox(), you would call ShowWindow() for the second window (in the same way you do it for the first one in WinMain()).
It looks like you have only copy-pasted someone's else code. You should get some idea of what it is currently doing first.

The second parameter is of const char* type (text), which means that you must not pass integer arguments, and TXTU (whatever it is supposed to be) is an integer.
And your msg() function should return a char (which is obviously not the thing you want).
