    C does not have built-in GUI capabilities, so you need to use external libraries or APIs. Two of the most common approaches are GTK+ (cross-platform) and the Windows API (Windows-specific).

    GTK+ Toolkit (Cross-Platform)

    Step 1: Install GTK+ On Linux:

    sudo apt-get install libgtk-3-dev

    On Windows, download from gtk.org and configure your compiler.

    Step 2: Write a Simple Program

    #include <gtk/gtk.h>

    static int counter = 0;

    void greet(GtkWidget *widget, gpointer data) {
    g_print("Welcome to GTK\n");
    g_print("%s clicked %d times\n", (char*)data, ++counter);
    }

    void destroy(GtkWidget *widget, gpointer data) {
    gtk_main_quit();
    }

    int main(int argc, char *argv[]) {
    GtkWidget *window, *button;
    gtk_init(&argc, &argv);

    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    g_signal_connect(window, "destroy", G_CALLBACK(destroy), NULL);
    gtk_container_set_border_width(GTK_CONTAINER(window), 20);

    button = gtk_button_new_with_label("Click Me!");
    g_signal_connect(button, "clicked", G_CALLBACK(greet), "button");
    gtk_container_add(GTK_CONTAINER(window), button);

    gtk_widget_show_all(window);
    gtk_main();
    return 0;
    }
    Copied!
