First you have to make active the group (or a window) where to place the widget by calling begin() on that group and then just make the widget using new operator. After that you might need to call redraw() upon that widget. The parent group will be responsible for that widget an it will destroy this widget when the group will be destroyed itself. You can place all the code within the Callback field in fluid widget attributes (in c++ tab) and fluid will create callback wrapper for you :-), like
my_group->begin(); (new Fl_Button(20, 30 ,50, 20, "My button"))->redraw(); !!!!!!!HOWEWEWER!!!!!! Be aware that completely new widget will be created with every call to the callback, which would obscure the old one and this is usually not good approach. Also for that reason you might consider to create the widget from the start and make it invisible. Then you just call show() and hide() uppon that widget (in your callbacks) for the widget to appear/disappear. In the callback you usually create only new instances of top-level windows (like for many documents) which then create all comprising widgets in its constructor.
