This is how i have declared the entry

Gtk::Entry* entry_rapidrate;
entry_rapidrate->set_text("hello");

You didn't create any widget, you simply declared a pointer to a widget and didn't even initialize it to a value. This is pretty basic C/C++, so I would suggest doing a bit of studying of basics first.  In any case, you would need to do something like:

Gtk::Entry *entry_rapidrate = new Gtk::Entry();

entry_rapidrate->set_text("hello");

// later when you're done using the entry, free it so you
// don't leak memory
delete entry_rapidrate;
