I have found a solution here:
http://stackoverflow.com/questions/20134421/can-a-windows-gui-program-written-in-lazarus-create-a-console-and-write-to-it-at

uses
Windows;
begin
AllocConsole; // in Windows unit
IsConsole := True; // in System unit
SysInitStdIO; // in System unit
// Now you can do Writeln, DebugLn, ...
end.
