I'd put the buttons into a GtkTable for layout. You can set a cell horizontal and vertical padding which you should be able to adjust to get the spacing you want. Be aware that the user can change the font / display resolution / text direction behind your back, so you need to be quite flexible about how you handle resizes.

Colour and fonts are best set in a gtkrc file so the user can change it, rather than being wired into your app. Set names for your widgets and then write a gtkrc file like:

# style for button background
style "background_style" = "default"
{
       bg[NORMAL] = "#0"
}

widget "*background_widget" style "background_style"

Now anything called "background_widget" will be painted with a black background when in the normal state. You can set fonts in the same way.

 So far I have only tried to compile this stuff on linux

You might try the gtk-win list for win32 tips.
