在Ubuntu上使用C++开发图形界面可选择以下库/框架，以下是安装、示例代码及编译运行的基本步骤：

1. GTK+

安装：sudo apt update && sudo apt install libgtk-3-dev

示例代码（创建带按钮的窗口）：

#include 
static void activate(GtkApplication *app, gpointer user_data) {
    GtkWidget *window = gtk_application_window_new(app);
    gtk_window_set_title(GTK_WINDOW(window), "Hello GTK+");
    gtk_window_set_default_size(GTK_WINDOW(window), 200, 200);
    GtkWidget *button = gtk_button_new_with_label("Click Me");
    g_signal_connect(button, "clicked", G_CALLBACK(gtk_main_quit), NULL);
    gtk_container_add(GTK_CONTAINER(window), button);
    gtk_widget_show_all(window);
}
int main(int argc, char **argv) {
    GtkApplication *app = gtk_application_new("org.gtk.example", G_APPLICATION_FLAGS_NONE);
    g_signal_connect(app, "activate", G_CALLBACK(activate), NULL);
    int status = g_application_run(G_APPLICATION(app), argc, argv);
    g_object_unref(app);
    return status;
}

编译运行：
g++ pkg-config --cflags gtk±3.0-o hello hello.cpppkg-config --libs gtk±3.0 && ./hello

2. Qt

安装：sudo apt install qt5-default qtcreator（含IDE）

示例代码（带按钮的窗口）：

#include 
#include 
int main(int argc, char *argv[]) {
    QApplication app(argc, argv);
    QPushButton button("Hello Qt!");
    button.show();
    return app.exec();
}

编译运行：
qmake -project && qmake && make && ./your_executable_name

3. FLTK

安装：sudo apt update && sudo apt install libfltk1.3-dev

示例代码（带按钮的窗口）：

#include 
#include 
#include 
void button_cb(Fl_Widget *w, void *data) {
    printf("Button clicked!\n");
}
int main(int argc, char **argv) {
    Fl_Window *window = new Fl_Window(300, 200, "Hello FLTK");
    Fl_Button *button = new Fl_Button(100, 80, 100, 30, "Click Me");
    button->callback(button_cb);
    window->show(argc, argv);
    return Fl::run();
}
