PHP GTK and Glade questions

Hello,

Sorry about my newbie questions but I have not found answers.

1) I need something like confirm window known from JavaScript (user chooses if execute or do not execute an action). Is this kind of windows in PHP-GTK?

2) In my application there is a window where program settings will be. Is there some kind of window which has no maximize and minimize icons (only close icon) in the upper right corner? I would like to window does not appear in windows status bar. I tried to set "skip_taskbar_hint" and "skip_pager_hint" properties to true, but window still appears in the status bar. Why?

3) I need to choose two paths in a local drive. First to concrete file and second to a concrete directory. These paths need to be mentioned in input text boxes after user these paths selects. I would like to know what components use to select this file and directory.

4) This code opens new window where user chooses settings. How to close this window? (but main window needs to be still open).

$this->glSett   = &new GladeXML($this->mProgramPath.'/'.$this->mGladeGui, 'settingWindow');
$this->dlgSett = $this->glSett->get_widget('settingWindow');      
$myClassInstance = new MyClass();
$this->glSett->signal_autoconnect_instance($myClassInstance);

Thank you for your help.
