my $splitter = Wx::SplitterWindow->new($this, -1);
my $tree = Wx::TreeCtrl->new($splitter, -1);
my $something = Wx:Something->new($splitter, -1);
$splitter->SplitVertically($tree, $something);

i was at the same point like you are now two or three months ago...
i suggest to read and rewrite the examples depending on your wishes... they
have everythin you need...
as soon as you understand them, you'll be able to use the wxwindows docs to
programm your stuff

> - How can I create multiple frames for my application? How can I load and
unload them?

check the samples (splitter.pl)...
my way to create multiple frames:

my $splitter1 = Wx::SplitterWindow->new($this, -1);
my $splitter2 = Wx::SplitterWindow->new($this, -1);
my $tree = Wx::TreeCtrl->new($splitter1, -1);
my $something1 = Wx:Something->new($splitter2, -1);
my $something2 = Wx:Something->new($splitter2, -1);

$splitter1->SplitVertically($tree, $splitter2);
$splitter2->SplitVertically($somethin1, $something2);

> I'm also having problems with toolbars

Wx::Image::AddHandler(new Wx::PNGHandler);
my $toolbar =
$this->CreateToolBar(wxTB_HORIZONTAL|wxNO_BORDER|wxTB_FLAT, -1);
$toolbar->SetToolBitmapSize(wxSIZE(22,22));
$toolbar->AddTool(0, Wx::Bitmap->new('icons/download.png',
wxBITMAP_TYPE_PNG), 'download emails');
$toolbar->AddSeparator;
$toolbar->AddTool(1, Wx::Bitmap->new('icons/new.png', wxBITMAP_TYPE_PNG),
'new email');
$toolbar->Realize();

a little part of my email program written with wxPerl... you could run in
problems if you haven't all of "wxTB_HORIZONTAL|wxNO_BORDER|wxTB_FLAT"

hope it helps
